Terry, Very interesting. I have written Water but not heard back yet. I sent him a very brief description of what I had done and asked whether his graphic screen could be used real time for data display. Mine is set up to display in red if data is out of limits, yellow if marginal, and green if normal. If the pilot sees green everything is sweet. Since he is also using Excel, some combining might be possible. Thanks.

Yeah, Ron, the Beach Masseur job had to be curtailed when the price of oil went up and I couldn't afford to buy the oil and pay the customers as well (Brazilian cane ethanol just isn't the same....) Actually, I'm currently waiting in sunny UK (well, last weekend was sunny) for the Brazilian authorities to grant me a business visa to return there and continue running production for a factory near Rio producing Sport Planes and also Lancairs. The current production is mainly Jabiru aircraft and of course engines, and we also provide Jabiru engine support for Brazil. The company can be seen at www.cimaer.com.br. Anyway, Best Regards to all Listers who were wondering where I'd gone. Actually, I never left the list and monitor it most days from wherever I can access the Interweb. Cheers, Andy. ________________________________________________________________________________

----- Original Message ----- From: Ivan Sent: Sunday, September 28, 2008 9:44 PM Subject: [jabiruengines] prop pitch-RPM vs carburetor full rich relationship I have a J-250 3300. I just had my JSB done regarding the prop mounting. I cant seem to get the prop pitch of the ground adj Sensenich prop the same as before but not sure if it is a problem anyway. I think I have it set a little more pitch than before. I am only getting 2810 RPM full power climb at 83 KIAS. My cht/egt's seem good. Since the Bing altitude compensating carburetor needs a certain RPM??? to run full rich on climb, I am wondering if 2810 RPM is good enough to run full rich? I used to climb out about 2900-2950 as set at the factory. Cruise is no issue at 2850 with good temps. As I remember?? I think the lower limit of "full rich" with the Bing is at 2800 RPM but do not know for sure. If necessary I can decrease the pitch a bit. Temps will not be an issue now since the winter is here but I still should make sure I am running full rich on climb.

Good to hear from you Andy. Say, would you know any good CHT numbers for Jabiru engines that have the CHT probe affixed right on the head, rather than under the spark plug with the sensing end of the thermocouple sticking up into the cooling airstream? Maybe you've seen the recent thread concerning this change of placement. If not, I'll bring you up to speed on what I did.

Subject: CH701 with Jabiru 2200
Date: Sep 29, 2008
The following statement was taken from "STOL Updates from Zenith Aircraft Co." e-mail I received today: "What made this CH 701 unique was the installed powerplant: a Jabiru 2200...." It is not clear to me what is so unique, as I and others have been flying our CH 701s behind a Jabiru 2200 since 2002. In fact, you can see my CH 701 on ZAC's web site with the note it has a 2200.

Subject: Re: Kitfox-List: CHT probe placement
Date: Sep 30, 2008
I did some tests today regarding the CHT probe placements on my Jabiru 2200 engine. I'm cross-posting this so others can benefit, and even make assumptions regarding other engines, perhaps. I was wondering out loud about how the different mounting locations for the thermocouple probes might affect the readings of the cylinder head temps. During my recent overhaul, I decided I didn't like the "under- the-spark-plug" mounting location, so I changed to a location that required me to drill into the head, tap it for an 8-32 machine screw...actually a socket head cap screw...and affix the proper electrical terminal onto the end of the t'couple probe...after removing the spark plug terminal of course. First I went up and got some CHT numbers as the basis for comparison. I noted that cyl. #1 ran 317, 327, and 340 F, during various phases of flight. Noting these, I then took the probe from cyl #3 and attached to it a spark plug terminal (12mm), and installed it onto the spark plug that lives over the exhaust valve on #1 cylinder. I first removed the spark plug washer like Jabiru says to do, installed the probe/terminal, then reinstalled the spark plug washer, and reinstalled the plug. Then went flying again. Here is how I'll report the numbers....I'll call the new location (the machine screw termination) CHT, and the spark plug termination, SP, as In (CHT/SP) The numbers I got were as follows (with an ambient of 61 F) (drum roll please)....initial taxiing= (250/220); taxiing further= (266/230); climbing out= (308/232); further climbing=(321/243); leveling off (not recorded for how long level)= (330/245); not noted what attitude, but not climbing=(334/249); climbing again briefly= (344/248) I noted that the max differential was 96 F, and the climbing EGT's were in the high 1200's. I didn't have enough hands, instruments or inclination to record every aspect of the test, but I got enough to satisfy myself that my new locations for the CHT probes work, and now I can rest assured that I'm not overheating the engine as I thought I might when I first started it up with this configuration. Needless to say, the CHT's now apparently rise more quickly, and if you're like me, and you've been accustomed to seeing it rise slowly and only into the low to mid- 200's, the ol' pucker factor rises just as quickly and the finger gets close to the panic button, but it's just numbers, and now that I've done some testing, I'll relax a bit on this subject at least.

Lynn, I have decided to use the factory holes on my 3300 and surface mount the sensors using the 8-32 machine screws. Did you use steel, stainless steel, or aluminum screws? I am thinking maybe aluminum if I can find them. I can guess what the issues might be. Jim Crowder ________________________________________________________________________________

I was not trying to slam ZAC, it was just interesting to me their use of "unique" for a 701 with a 2200. ZAC was extremely helpful and patient with my many questions while building the 701. Pete also was also extremely helpful as I figured out how to install the 2200 as well as operate it. At that time, ZAC felt the higher prop rpm with shorter blades of the 2200 would not be a good match for the 701 and preferred the Rotax 912. >From early on, I exchanged 701/2200 ideas with builders in England, Canada, Australia, New Zealand and the USA using the 2200 in a 701. It is good to see that ZAC now endorses the 2200 for the 701. Both ZAC and Pete are class acts. Chuck D. N701TX ________________________________________________________________________________

Here are some pictures for those interested in pursuing an alternate location for the CHT probes. tapping the hole thermocouple prepared and ready to install keeping the thermocouple clear of the spark plug socket I ran some tests with two thermocouples in place...one in new location, and the other under the spark plug....at one point 96=B0 F hotter at the "against-the-head" location, as opposed to having the t'couple up in the airstream.

Well Since the engines are run in for an hour and then treated with storage oil, you will see a =B3dirty=B2 spark plug when you remove them before you star t the engine for the first time.

Re: JabiruEngine-List: Factory tested ??Jim, I got a question about setting up a prop for the 3300A engine with the economy tuning kit installed. As I see it all one has to do is assure that the ground run RPM at full throttle is over 2800 RPM and that the inflight RPM full throttle straight and level doesnt go above 3150-3300. If these specs are followed we can be assured that we are running full rich/full power upon takeoff and lean in cruise. Does this sound right to you?

Ivan, Ground static and max in-flight RPM's do not guarantee that you have the right size jets for correct mixture. Although, being way off the correct mixture will likely cause you to fall short of any RPM targets you have. Jet sizes aside for now, your static RPM will vary greatly depending on your prop. I have the Senenich wooden W64ZK49 prop in my 601XL and it gives me a static RPM around 2650. Max level flight RPM is around 3150. Other people with the same airframe/prop/engine combination get different results due to the inherent variations. For in-flight confirmation of mixtures, having EGT information is very helpful. The Jabiru factory documentation says that the EGT target for takeoff is 1184F and the cruise target is 1256F. If I remember, Pete from Jabiru recommends takeoff EGT's in the 1200-1250 F range and cruise EGT's in the 1350-1400F range. Depending on whether you are above or below these targets will tell you that you need to lean or richen your mixture. The variation between cylinders will confuse the matter a bit as you may see some cylinders will be above the target and some will be below it. I have spent a good part of my phase I flight test period trying to find the 'sweet spot.' Good luck, -------- David Gallagher 601 XL, first flight 7/24/08. In Phase I flight test.

Ivan, If you say your jets were tuned at the factory, then I guess you are flying a Jabiru airplane. (I do not know what you have) The jets that Jabiru installs onn the production line are meant to work the best for their Jabiru airframes and may, or may not, be optimum for other installations. When they built my 3300 engine, they did not know what type of airplane it would go in. As it happens, I put it in a Zodiac 601XL with a fixed pitch wooden prop. In this application, the load that the engine sees in flight is much different than on a Jabiru airframe. As Pete at Jabiru USA said up front, and I have confirmed through flight testing, the jets in my 3300 engine were too large (rich). I have had to go down one size in both the main and needle jets to get the right mixture. As to finding the 'sweet spot,' that is too complex a discussion to just attach to this thread. The 601XL installation has all sorts of turbulent airflow into the carb which causes all sorts of variability in mixture to the individual cylinders. I am close to publishing the results of my testing in a separate post in the near future. Good luck, -------- David Gallagher 601 XL, first flight 7/24/08. In Phase I flight test.

Thanks Dave, Sorry I did not mention that my application is an S-LSA J-250. All was set at the factory. I had to have my prop removed so when it was placed back on the Sensenich ground adjustable pitch is not exactly as it was before. I put a mark on the dial before removing it but the numbers are so close that even a bit off changes the pitch-RPM a lot.

Subject: Electroair direct fire ignition system in a Jabiru
2200
Date: Oct 21, 2008
Here's the info on the Electroair direct fire ignition (www.electroair.net) system that I installed on my Jabiru 2200 engine in my Kitfox. First off, some history....why did I go with an after- market ignition system instead of the stock Jabiru ignition?....I thought there might be a better/more modern way to fire the plugs than the old system, and I became tired of having to change rotors after the recommended 200 hours of use. Also, I was reluctant (stubborn) to glue the rotors on as recommended. After having found that it was indeed necessary to glue them on, and having some success using that method, I decided...during a rebuild of the engine...that I would leave all the distributor components off when reassembling the engine, and go with the Electroair direct fire system. Electroair had begun development on a component to replace one of the Jabiru distributors. This would retain the other distributor as the other half of the redundant ignition system. I, being stubborn, wanted to do away completely with the Jabiru ignition, and asked Electroair if they would design a system that would use a trigger wheel and two magnetic pickups, similar to their 6-cylinder engine systems. They would do this, but I had to make my own bracket to hold the two pickups, as they did not have access to a Jabiru engine for designing the prototype bracket. I agreed to this and ordered the ignition kit. To make a long story short (and to create some drama for a possible future magazine article), I got the system installed, and it is working beautifully. There were some minor "growing pains" as we sorted out some installation issues, but these are in the past, and I am now flying with the assurance that I won't be bothered down the road with loose rotors, loose distributor caps, leaking distributor shaft seals, and scored shafts that I have experienced in the past. The kit originally arrived weighing about 13 lbs, and by cutting the harnesses and spark plug wires to a more suitable length for my airplane, I got the weight down to about 11 lbs. I removed the Jabiru distributors, drive gears, caps, rotors, coils, and plug wires, totaling exactly 5 lbs. So the increase in weight for the Electroair system was about 6 lbs...a small weight penalty for such a modern dependable ignition system, and one that allows for future ignition modifications as well, which I will be looking into.

We now have 230 hours on the airplane and engine.My Son contacted Jabiru but I think the prices they are offering are a =C2-w ee bit high, I may be wrong, but I thought I'd throw it out there and see wh at advice you Jabiru wonks could add. =C2-I am also looking for accurate p art #'s so if I go to a local supplier I'm assured that I'm getting =C2-th e right parts.Thank you for yur time and cionsideration.Sincerely,Pete Paris =C2- ------------------------------------------------------------ Art School Click to become an artist and quit your boring job. http://tagline.excite.com/fc/JkJQPTgLBDtkjc2DaWmjWez7C50Sxf8ZUexPyP3AmlDiS0B yanP4JQ/ ________________________________________________________________________________

JabiruUSA doesn't seem to have a source for the recommended smooth air elbow recommended from the airbox to the carby intake. Does anyone have a source? My local auto parts stores just looked at me when I told them I just wanted to look through their hose selections to find one. Seems if you can't tell them what car it goes on, you are out of luck .. It is 2 and one quarter inch inside diameter in a 90 degree elbow. This may or may not be the part they refer to as the Cobra Head. Obviously, one did not come with my FWF kit, just scat hose. Thanks .. Jeff ________________________________________________________________________________

The hose geometry will depend on each airframe and FWF layout, of course, but FWIW, on my Murphy Rebel, with the std. mixer box mounted straight back of the engine and high, a Gates brand #20748 radiator hose fitting works well for turning the corner. The turn is a little wider than 90 deg., perhaps 105-110 deg. Another short piece of straight 2.25" hose completes the run up to a bottom exit from the mixer box. A photo is at at http://n254mr.com/node/572 . There's a lot of stuff in the way in this photo, including Magnecor plug wires dangling about, but you ca n get the idea. It's an AeroCarb installation, but the Bing intake geometry would be much the same.

Gary I purchased from the local Australian agent SGESCO.MAX. They provide tel advice if there is a problem. The part number given is 333015038 and it also displays engine hours in an LCD display. The installation details are provided by VDO in a flyer which tells how to connect it to drive it from the alternator, the neg earth or the small HE sender supplied. They also supplied a noise suppression diode which I am using with the alternator connection.

Craig: It is still the same part number but the cost has escalated to $13.40. However, that is over $80 less than I paid for the Cobra head I received from Jab which was way too big to fit in the small space available. Thanks for the info on intake hoses dot com. I was just about to google hoses when the hint showed up in my in-box. Will order one today.

I built my own "air straightener/divider." It was a lot of work, and I can't say as it gave me any benefit...maybe, but I'm not positive. Here's a picture. I started out with the curved fiberglas tube which I built, laying fiberglas over a section of PVC plumbing. I used it for awhile just as a curved tube, then later cut it along the vertical axis and added the air straightening vanes, and reassembled.

<> I've been chasing a charging problem on an aircraft in my hangar for a few years. J430 3300 Jabiru. Some time ago the agent changed the alternator coils for new ones whilst doing some elimination fault finding and the problem seemed to be cured for a year or so though it was never clear what the problem was. However a few flights recently have shown some intermittent charging and on the last flight the radio packed up as the voltage was so low. The battery situation wasn't clear as it had been swapped many times for a spare so we started with charging the battery fully on the ground. Still no charge when running and as I began to start with measuring the AC from the coil I noticed some scorching in the AC lead connectors, see attached. Examining the scorched one it came off in my hand. I gentle pull on it's partner and this too also came off. The ends on the wires were stripped and 'tinned' but it is clear from examining the crimps they have never been either soldered or crimped to grip on the conductor. Suggest you give your AC connections a good pull next time you have the cowlings off in case yours have the same problem which may manifest itself at an awkward moment. May also be worth sliding the insulation back and examining the crimp appearance or chopping them off and putting better ones on.

Yes these were the originals. You have it covered already and I suspect Ben came across the issue many years ago.... The first Jab engine I got I looked the connectors over and they looked good so I just used the 1/4 blades in them and heat shrinked over the lot. They are still on the plane and it's done 1000 hrs with good volts throughout. It was likely that these badly fitted ones could have lasted as well. I'm not sure if my Esqual engine has them changed or not, it's an age thing.....

Hi Bill. only effect was battery volts dropping thought not conclusively. Charge light didn't come on for instance. Plane was built in 2004. New coils (with dodgy crimps) were fitted in 2006 or 7.

Thanks, Bill of Georgia -----Original Message----- From: James, Clive R <clive.james(at)uk.bp.com> Sent: Thu, 30 Oct 2008 5:49 am Subject: JabiruEngine-List: Found it at last-Coil feed wires not crimped on new alternator coil. <> I've been chasing a charging problem on an aircraft in my hangar for a few years. J430 3300 Jabiru. Some time ago the agent changed the alternator coils for new ones whilst doing some elimination fault finding and the problem seemed to be cured for a year or so though it was never clear what the problem was. However a few flights recently have shown some intermittent charging and on the last flight the radio packed up as the voltage was so low. The battery situation wasn't clear as it had been swapped many times for a spare so we started with charging the battery fully on the ground. Still no charge when running and as I began to start with measuring the AC from the coil I noticed some scorching in the AC lead connectors, see attached. Examining the scorched one it came off in my hand. I gentle pull on it's partner and this too also came off. The ends on the wires were stripped and 'tinned' but it is clear from examining the crimps they have never been either soldered or crimped to grip on the conductor. Suggest you give your AC connections a good pull next time you have the cowlings off in case yours have the same problem which may manifest itself at an awkward moment. May also be worth sliding the insulation back and examining the crimp appearance or chopping them off and putting better ones on.

Clive, I noticed the harness loom tubing had melted at the connection from the alternator. I think the connectors I used were not compatible with the ones from the alternator. I cut off the connectors and soldered the wires, everything is "cool" now. This had been a common problem in the past. Chuck D.

I finally got the EIS 4000 to report accurate data, without hopping all over the screen, I installed a Radio Shack 273-105 ferrite filter (as suggested by Sandy at Grand Rapids Tech) around the input wire bundle, and that seems to have cured it. After installing the filter, the thing acted up once during taxi, but never after that....in .4 hrs of flying. I have another filter to install on the EGT and CHT probe extensions, but I may not need to do that....we'll see.

Subject: Re: Fuel Filter
Lynn, et al, Be very cautious when buying the latest version of the "Clearview" type of fuel filter. They are now marketed by several companies, among them "Mr. Gasket". The design has been re-engineered to make them easier to manufacture and the result is no longer suitable for any vehicle application and certainly not aircraft IMHO. The original Purolator filter (mine is circa 1994) had one end and the center section machined as one piece and the center section was round which yielded threads that gave a circular contact on the end that screwed on. Now the center section is a flat cast piece. The parting line runs through the center of the part and the two sides are MISALIGNED (!) so that the ends will not stay square to it when the filter is assembled. The result is that the o-rings get damaged and leak. In addition this new center section is only about 1/8" (3.2mm) thick so the area of thread engagement to the threads in the end pieces is very small. In the original the barbed fittings were part of ends making for a bit of a PITA since you had to buy a specific size to match the fuel line used in the application. The new version has threaded ends and comes with a set of plastic barbed fittings so one size fits all, however, the ends are chromed and the "overspray" (for lack of a better term) into the first two threads makes it necessary to chase the threads if you wish to use metal fittings. If you wish to investigate for yourself, I recommend you remove the filter from its packaging and inspect it right there on the store counter. If they make you buy it first at least you won't have to make a return trip to take it back.

Bob, >From an user of SU carbs in English cars: The symptoms are of a rich mixture which comes about when you open the butterfly (mixture mass flow control) but the slider (air valve control) is stuck closed. The BING carb must have - just like SUs - some sort of damping system to preclude the slider to jerk open as you open the throttle. SUs do it via a small reservoir filled with very light oil and a plunger. Oil can leak through the plunger at a prescribed rate, and this controls how fast the slider opens. I do not know how this is accomplished by BING but it is worth some study. If the slider is sticking, as you open the throttle fuel is sucked from the needle well but the slider does not allow more air flow and this results in an overly rich mixture and black smoke. Check the slider for smooth motion from fully closed to fully open. If some stickiness is noted, a cleaning is in order. These carbs are very, very sensitive to dirt, dust or other miniscule things that may get in between the slider and guide. Worst case scenario is a punctured rubber membrane (diaphragm) which pulls the slider up. A tiny leakage will induce the described behavior also. It will not matter greatly above a certain speed. Do not change needles unecessarily. Good hunting!

I have a Clearview that was sitting in my Harley parts bin when I bought the Mr. Gasket POS, so the Mr.Gasket unit went back to the auto parts store and the Vibraglide filter went airborne.One more thing about fuel filters. If you live in a country subject to the Ethanol swindle as we are in the USA be careful NOT to use any kind of fuel filter with a paper element. If water should drop out of suspension it will coat the paper and, well, you might as well try to fly with the fuel valve closed. This isn't just my opinion, Rotax mentions this specifically in their manuals. Rick On Tue, Nov 4, 2008 at 8:11 AM, Jim Crowder wrote: > Rick, > What filters are you now using?

Rick- I've got the "real" Purolator filters, but they *do* have the cast center section as you say. But mine are leak-free and have been right along. I know what you mean about the center section being kind of crappy, machining-wise, and the old round one was a better design, but like everything else, the "design be damned, we're gonna build it cheap" school of thought has taken over. I just removed the electric fuel pump from my fuel system, and in so doing, I had to find another way to go from 5/16" fuel line down to 1/4" fuel line, so I just changed one end on my Purolator filter and that was that....5/16" cap with the built-in barb on one end, and 1/4" cap with built-in barb on the other end. And these caps have the nice smooth barb which is a joy to install and remove the fuel line from. I've seen the multi-size end caps on the "non-Purolator" filters, and they are crap...the "one size fits all" mentality at work again. Just for the record, before I removed the fuel pump and fuel pressure gauge sending unit from my system, I measured the fuel flow right at the carb, and it was 11.25 gallons per hour. With the fuel pump and fuel pressure gauge sending unit removed, and 1/4" fuel line in it's place, the flow was 13.6 gallons per hour. This was measured (with about 5 gallons in each of the two wing tanks) by taking the float bowl off and timing the flow of fuel through the carb (with the new 3.7mm float needle seat) for one minute, multiplied by 60. I can now climb as steeply as desired, and the engine doesn't go lean or stumble from lack of fuel.

Subject: What's My Contribution Used For?
Dear Listers, Some have asked, "What's my Contribution used for?" and that's a good question. Here are just a few examples of what your direct List support enables. It provides for the very expensive, commercial-grade T1 Internet connection used on the List insuring maximum performance and minimal contention when accessing List services. It pays for the regular system hardware and software upgrades enabling the highest performance possible for services such as the Archive Search Engine, List Browser, and Forums. It pays for 19+ years worth of online archive data available for instant random search and access. And, it offsets the many hours spent writing, developing, and maintaining the custom applications that power this List Service such as the List Browse, Search Engine, Forums, Wiki and PhotoShare. But most importantly, your List Contribution enables a forum where you and your peers can communicate freely in an environment that is free from moderation, censorship, advertising, commercialism, SPAM, and computer viruses. How many places on the Internet can you make all those statements these days? It is YOUR CONTRIBUTION that directly enables these many aspects of these valuable List services. Please support it today with your List Contribution. Its one of the best investments you can make in your Sport...

Scenerio: 3300 Jabiru; Dynon DK180; Pulse/Revolution values are set (at) 6; tach wired to alternator with 1 amp fuse; Problem fluctuating tach readings on taxi testing. Readings: At idle 2000+/- RPM -- hand held tack shows 1050+/- 10; As I add throttle Dynon RPM drops to 1600; Slowly adding more power tach reading comes up then drops until it reaches full throttle and reads 2300 (static should be 2800).

Mack, I have the same A/C, engine and Dynon D180 as you. My tach reading is correct and rock solid. Lets see if we are hooked up the same. My alternator signal tee's off of one of the two big output wires up stream of the voltage regulator. This off-take wire has an in-line fuse holder and hooks up to the Dynon white/green wire for "left tach." In the Dynon set-up, double check your 6 pulses per rev set-up is on the same side tach you are wired to. Make sure you do not have any bad connections or shorts in this circuit. Maybe also change out your fuse to another one. Good luck, p.s. Unless you have a climb prop, I doubt you get 2800 static RPM on the ground. I see 2600 with the 64ZK49 that Jabiru supplies with their FWF kit. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 Phase I flight test complete 10/16/08 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=215127#215127 ________________________________________________________________________________

Paul, What EGT's are you seeing with the economy tuning kit? Also what is the transition RPM that you notice from full rich to lean? I have a ground adjustable prop so this adds a variable without changing anything on the carburetor. I am seeing EGT's (at 3500ft MSL) in the 1300's and my transition RPM seems to be at 2900. Thus on climbout at 85kts/2850 RPM I am not yet at full rich since I am less than 2900 RPM.

I am seeing 1375 F at peak which happens at about 2750. I usually climbout at about 3000 RPM with the EGT at 1325 F. Climbout is from 5300 FT most of the time. I do most of my flying between 10 and 13 K and tend to run the engine at 2900 for cruise. I guess I do not know enough about CV carbs to be able to say where the slide is at full throttle on climbout at 3000 RPM. It would be nice to be able to have a prop that could be adjusted in flight so the engine could develop max torq and HP when you wanted it. Maybe Jim or Pete can give us some insight about the CV operation at full throttle but less than max RPM when the engine is loaded down. -------- Paul Spackman Q-2 Jabiru 3300 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=216533#216533 ________________________________________________________________________________

The filter must be present in the system for the fuel flow test. The size of the filter should give consideration to allow adequate flow with a used filter.

No flames, but no failures either, in any of my three Purolator in- line glass fuel filters in nearly 600 hours of operation....and no gascolator, either. Just a header tank with the wing tanks feeding it, and a sumping point at the bottom. This serves the same purpose as a gascolator. It allows any crap that reaches the header tank to settle to the bottom, where it is "sumped" away the next time fuel is drained...the next day, hopefully. And unlike a gascolator, the capacity of this tank below the fuel outlet port is almost a quart, so you could get really lazy/inattentive and still not get any crap in the outgoing fuel...unless you shook the airplane really violently, then tried to fly it. Then you might get some floating crap into the outlet port. Guess what? Downstream from this header tank is the last of the three filters. And just for the record, I've got 19 hose clamps and more than that in potential points of leakage, if you count the barbed fittings that are screwed into the tanks, valves, filters, firewall pass-through, and carb. Oh, and by the way, this is a high-wing, gravity-flow system. I just found the figures for fuel flow that I posted back on Nov 5, and which I'll paste here: ***** Just for the record, before I removed the fuel pump and fuel pressure gauge sending unit from my system, I measured the fuel flow right at the carb, and it was 11.25 gallons per hour. With the fuel pump and fuel pressure gauge sending unit removed, and 1/4" fuel line in it's place, the flow was 13.6 gallons per hour. This was measured (with about 5 gallons in each of the two wing tanks) by taking the float bowl off and timing the flow of fuel through the carb (with the new 3.7mm float needle seat) for one minute, multiplied by 60. I can now climb as steeply as desired, and the engine doesn't go lean or stumble from lack of fuel. ***** Lynn Matteson Kitfox IV Speedster, taildragger Jabiru 2200, 593hrs Sensenich 62x46 flying again after rebuild, and new Electroair direct-fire ignition system; also building a new pair of snow skis On Dec 2, 2008, at 6:21 PM, Tim Juhl wrote: > > I've never seen a fuel filter on any of the production aircraft > I've owned or flown, just a gascolator backed up by drain points > in the tanks.

The Aircraft Spruce filter P/N 05-01030 seems to be serving me pretty well so far. I want to add a word of caution about the comment of using a smaller gascolator filter. I have the Spruce gaslocator that has a single layer mesh screen in it. I e-mailed Spruce about the mesh size and got a reply that it is 120 microns. They told me that they have a 74 micron screen available, but that it was not listed in the current catalog. I went ahead and bought a couple thinking that I would just use the smaller screen and no filter. I installed the new screen and performed and engine run. I could not accelerate past part-power and my fuel pressure at the engine was way low. I popped the old screen in and re-ran the engine without any problems. I threw the smaller screens out, added a filter into the system and never looked back. I could have spent some more time troubleshooting around the smaller screen but decided it was not worth the effort. The stock 120 micron gascolator screen and the 05-01030 filter passes the flow test and has around 50 flight hours with no problems. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 Phase I flight test complete 10/16/08 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=217488#217488 ________________________________________________________________________________

UNBELIEVABLE. that is a 75 deg. drop. i was starting out with the dams too small. you can learn a lot from this list if you go with the ones that know. thanks again. bobby N131BP 73 hrs. and i didn't have to pull the cowl after this flight. ________________________________________________________________________________

From: "Don Honabach" <don.honabach(at)pcperfect.com>
I'm having an issue where during cruise flight if I go full throttle either in straight and level or climb, the engine gets rough enough that it feels like it will quit. At this point, I obviously don't want to push the issue so I pull back on the throttle until the roughness goes away. Interestingly, I have no problem with full throttle roughness on take-off/climb-out. I also did some additional testing today and found that if I ease real slow into full throttle from cruise that I still get the roughness but not as bad and that the RPM will increase up to ~2,9xx and then start to degrade as I continue to add power along with additional roughness. Background info: Full Throttle Static RPM/Ground Run Up is ~2,800RPM. No issues with roughness. On my 601HDS, I have a 3300A with the Sensenich Carbon Prop (64"? 2A0J5R64Z-N) that was purchased from Jabiru USA/Pete K. back in 2006. Any help greatly appreciated. I've sent this same question to Jabiru USA and haven't gotten a response yet (sent last Thursday and sent another today asking for status). Initially thought it was the SCAT intake hose which I replaced with the rubber 90 degree elbow. Same issue with either intake method. Thanks!

It sounds like it may be too rich under the load conditions at WOT cruise. The fuel bowl is fitted with 2.25mm needle valve seat which is meant for gravity feed, but they have selected the power needle as a compromise. If you are using a fuel pump it may cause the needle valve seat to leak and overfill the fuel bowl causing excessive rich mixture near max rpm. Another cause of over rich mixture is due to the starting choke not fully closing due to friction in the cable.

Peter, Thanks for the quick reply. FYI, I have a low-wing design and during take-off I use an electric boost pump but during transition to cruise I turn it off and just use the engine driven mechanical fuel pump on the 3300A. Even with the boost pump, I don't exceed 3PSI (at least as much as I can trust the accuracy of the gauge at such low values and a narrow range). Assuming the needle leaking is the issue, is there a fix for non-gravity feed setups? As a side question, do those with gravity setups remove the engine driven pump? I'm assuming that if I turn on the boost pump during cruise and if I have a needle leak issue that the problem should be noticeable sooner or should be worse as the increased pressure will cause more leakage? I'll check the choke cable as well to make sure it is fully closing. Thanks!

Don I have the J3300 in a Quickie Q-200 and getting 170KTS at 3000 ft CAS but still not happy with the higher power settings and feel it has more potential. Yes you could try the boost pump and that would indicate if there is a problem with the needle valve seat. It is possible to almost stop the engine if it gets too rich even at WOT. The setup is supposed to be OK at 3PSI. Some have fitted a fuel pressure regulator but if you are sure you have 3PSI up to WOT I don't see any value in adding another fail point. Maybe it is the choke. The return spring is not very strong.

Don, Check you EGT span.

Don, Have you played with your jet sizes at all? I had a similar issue with being just a little rich at takeoff, but way too rich at WOT in straight and level flight. I had one speed run in which I had two cylinders actually go so cold in EGT that they shut down on me. That is the benefit of having instrumentation on all cylinders. I went from the stock 255 main jet to a smaller 250. This helped out a lot. Interestingly enough, there is an interaction between the main and needle jets, even at WOT, when the main jet is supposed to be in control. I found this out when I started to tune in my cruise EGT and went from a stock 285 needle jet to a smaller 280. Going to the smaller needle jet made my WOT a little too lean now. I went back to the larger 255 main jet and I am pretty happy with it now. Throw into the mix that I also went to a rubber intake hose with a flow divider to even the EGT spreads across the cylinders. Your results will certainly vary, but that is why they call this experimental, right?

don, i have read some builders have removed the mech. pump with a gravity set up. very easy to make a cover plate where the mech. pump attaches. a leaky needle valve can be a bad seat or needle, or your system is overpowering the float. bing can supply a new seat or needle. a pressure gauge that covers a very narrow pressure range can be had for less than $20. if you are overpressuring the carb it will leak. i think first i would want to know the fuel pressure, then decide the fix. i have also seen my carb leak and run smooth on the ground. bob noffs ----- Original Message ----- From: "Don Honabach" <don(at)pcperfect.com> Sent: Tuesday, January 13, 2009 12:55:09 AM GMT -06:00 US/Canada Central Subject: RE: JabiruEngine-List: 3300A - Full Throttle Roughness Peter, Thanks for the quick reply. FYI, I have a low-wing design and during take-off I use an electric boost pump but during transition to cruise I turn it off and just use the engine driven mechanical fuel pump on the 3300A. Even with the boost pump, I don't exceed 3PSI (at least as much as I can trust the accuracy of the gauge at such low values and a narrow range). Assuming the needle leaking is the issue, is there a fix for non-gravity feed setups? As a side question, do those with gravity setups remove the engine driven pump? I'm assuming that if I turn on the boost pump during cruise and if I have a needle leak issue that the problem should be noticeable sooner or should be worse as the increased pressure will cause more leakage? I'll check the choke cable as well to make sure it is fully closing. Thanks!

That sounds like a fuel delivery problem to me. Possibly a fuel pump not working properly when hot. If you have a fuel flow meter check your fuel flow as you approach full throttle. If yu have a fuel pressure gauge check that there is no drop in fuel pressure as the engine warms up .

The way to tell an over rich condition is to check the plugs. There will always be a good dose of soot on them if you land immediately. The fuel flow and pressure tests will show a rich condition too. Generally an over rich condition makes the engine sluggish and you start to have problems as you pull the throttle back as the plugs have to clear themselves enough to keep the engine running. One other problem you may have is low octane rating on the fuel. That could sure cause your engine to get rough at top end rpm.

As a firm believer in doing the easiest, cheapest thing first, check your tank venting. Next, do a plug check. Let the engine enter its rough running, shut the engine off and glide in. Plug color is an inexact method, per the Bing manual, but if your engine is running so rich as to run rough you should see the fuel contamination on the insulator. Worth what you paid for it.

Any engine running that rich, long enough, will leave lots of soot on the bottom of the plane and it will be caked up well in the exhaust too. Have a look.

Even assuming the incoming charge is aligned properly, near WOT there is a large increase in fuel dumped at the end of the collector feeding #1 and #2 and this will show up on the plugs as suggested by Noel. I have been experimenting with a 1.5L tapered plenum in place of the Jab collector and the effect near WOT is dramatic causing breakdown and black smoke. Because of internal losses the Jab collector does not normally breakdown , but will usually run rich on #1 and #2 when the butterfly is near fully opened. At smaller throttle settings the butterfly turbulence probably contributes to even distribution of the charge. I discovered that it is not easy to design an intake to be fed from the end, it should be fed from the bottom but I have no space.

Don, Maybe your air intake system is acting - or is designed to act - as a ram charged? Contrary to what was stated before, you might be running LEAN, because your jetting cannot compensate for additional air mass rammed in during cruise. Failing that, check any and all rubber sleeves you might have in your intake manifold. Just one allowing "false" air into the intake tube will make your engine rattle and shake in a frightening manner!

Don: I believe Jon's DVD "3300 Engine Installation" video may have the answer to your problem. This was shot by Jon at one of Pete's engine installation seminars. Pete says on the video that at wide-open-throttle if you are getting too much fuel it would result in cooler EGT's and shaking. If your EGT's are closer to 1,000F than 1300F it is running cool due to the rich mixture. He says the solution is a smaller main jet. He says about two-thirds of the Jabiru engines have had to decrease their jet size. At another point he says they are shipped with 285's and you should ask for the next lower. bingcarb .com has a good book on the carb and it helped me with carb problems on our first 3300 on a 601. Pete also said that they would be carrying the smaller jets but you can also talk to the experts at Bing which I believe is in Kansas. For information on the 3300 installation I think Jon's DVD is a must have. Five hours of excellent information.

I just wanted to take moment and thank everyone that responded to my question both on-list and off (WOW - just absolutely amazing the response - THANK YOU!). >From the various suggestions I decided that I needed to do a bit more investigation... During take-off AND WOT the EGTs on the right side of my engine are significantly higher than the left. The max difference being ~1400 versus 1100F. However, during cruise, everything tends to even out but now my left side (or at least cylinders #6 and #4) have higher EGTs than the right side in general (~1359 verus 1290). What is interesting is that my max RPM on take-off at WOT is ~2,850 and there is no roughness at all despite the same EGT profile. In contrast, when I do WOT in cruise the RPM maxes out at 3,000 and the roughness is pretty bad and starts at about 2900RPM and gets worse as the RPM increases. Also, pulling back so that the RPM is less than 2900 always gets rid of the roughness. So while the EGT profiles are essentially the same for both WOT situations, it would appear that when the engine is capable of going above 2900 RPM that the roughness occurs. Any thoughts?

Stan, The problem I have with that approach is that the selection of jets and needles is being made to compensate for a leaking float valve needle seat. The fuel needle seats are not all going to leak at the same rate. It seems to me that this is a poor way to tune an engine. I think the carb should first be assembled to Bing specifications for the application with pump feed. Then select jets and needles.

This was shot by Jon at one of Pete's engine installation seminars. Pete says on the video that at wide-open-throttle if you are getting too much fuel it would result in cooler EGT's and shaking. If your EGT's are closer to 1,000F than 1300F it is running cool due to the rich mixture. He says the solution is a smaller main jet. He says about two-thirds of the Jabiru engines have had to decrease their jet size. At another point he says they are shipped with 285's and you should ask for the next lower. bingcarb .com has a good book on the carb and it helped me with carb problems on our first 3300 on a 601. Pete also said that they would be carrying the smaller jets but you can also talk to the experts at Bing which I believe is in Kansas. For information on the 3300 installation I think Jon's DVD is a must have. Five hours of excellent information.

At this point, I obviously don't want to push the issue so I pull back on the throttle until the roughness goes away. Interestingly, I have no problem with full throttle roughness on take-off/climb-out. I also did some additional testing today and found that if I ease real slow into full throttle from cruise that I still get the roughness but not as bad and that the RPM will increase up to ~2,9xx and then start to degrade as I continue to add power along with additional roughness. Background info: Full Throttle Static RPM/Ground Run Up is ~2,800RPM. No issues with roughness. On my 601HDS, I have a 3300A with the Sensenich Carbon Prop (64"? 2A0J5R64Z-N) that was purchased from Jabiru USA/Pete K. back in 2006. Any help greatly appreciated. I've sent this same question to Jabiru USA and haven't gotten a response yet (sent last Thursday and sent another today asking for status). Initially thought it was the SCAT intake hose which I replaced with the rubber 90 degree elbow. Same issue with either intake method. Thanks!

Don, During static runs and during climb at WOT the manifold pressure is relatively close to 1 atmosphere but as the aircraft accelerates the vacuum increases and manifold pressure goes down . As manifold pressure varies, the distribution of the fuel/air mix through the collector varies, and similarly as the velocity of incoming air increases the turbulence and pressure profile through the system also varies. Alignment of the butterfly also alters the distribution to R or L because of the central vane in the collector. Possibly removing that vane would improve the situation, but that would be a challenge to the original development. Like you I have also watched as EGT goes moves to favour R or L as the plane accelerates to max cruise and on a couple of occasions encountered extreme roughness due to the engine "boxing" with uneven power R to L due to the difference in mixture. The engine started shaking. But if you follow Pete's advice you should eventually find a setting that is satisfactory. The charge distribution is never going to be perfect throughout the power range .

If this is any help I recall reading on the lists about the rubber coupling from carb to intake spider having a groove or step inside where fuel droplets cavitate and sit in a pool at times of operation. some have dealt to this by fitting an 'inner' sleeve tapered to make a smooth transition with no step.

Don, Other than the smooth 90 degree rubber hose, the other thing I did to solve the *EXACT* problem you have was to get a smaller MID jet. I think, like David, I went from a 285 to a 280. I don't have the paperwork with me, but I'm pretty sure thats what it was. The jet & the intake are the only things I have changed. My EGT's looked just like yours in the graph. ..lance -------- Zodiac XL/Jab 3300 http://lancegingell.com Read this topic online here: http://forums.matronics.com/viewtopic.php?p=224867#224867 ________________________________________________________________________________

Clive, I've had some positive results in fixing my roughness issue, but I'm still working out the details. Here's what I've got so far... I appear to have an air intake issue. Flying without the air intake system and just the carb open to the cowling area and the plane flies extremely smooth. This fixed the roughness for everything except the last 1/4" of throttle travel. Repitching the prop so I had an in flight max of ~3300 RPM fixed the last 1/4" of roughness. Before the pitch change, my max out in straight and level was 3000 RPM. I'm going to be installing various modified air intake setups over the next few weeks and will post my results. For what it's worth, after re-pitching and flying without the air intake system, the plane is amazing. I've gained about 5 to 10 MPH in speed and 300 feet per minute or more in climb and the engine is much smoother in all RPM ranges. I'm really excited about getting a good intake system designed :) now that I'm seen the "other side" of this engine.

J I would recommend against using Aerocarb especially on the J3300 based on personal experience. I was supplied with an Aerocarb with no Teflon liner. The slide worked on anodized metal to metal and jammed hard. The slide is pulled and pushed by an outrigged lever which causes the slide to twist and jam whenever pressure is applied. The attachment to cable is off centre and not even co planar with the slide. A Teflon liner is offered on the website but my several requests were ignored. I packed it with grease but it still jammed under the vacuum at low throttle settings and any attempt to quickly open throttle for a missed approach makes it jam harder because of the offset cable attachment. I attempted to discuss changes to the design but was abused. I have a copy of the correspondence. When I asked for a refund I was told to sell it on eBay. I would not have the conscience to give it away .

Thanks Don, mine is just the last bit and only at high revs. In the climb at 2800 it's smooth enough but then that a different situation to 3000 plus. I will drop off the scat from the carb for elimination of that issue, that's a great idea. I have oversized scat tube on the carb which I'm hoping will help with airflow but then I suppose that could be the cause.

What is interesting is that my max RPM on take-off at WOT is ~2,850 and there is no roughness at all despite the same EGT profile. In contrast, when I do WOT in cruise the RPM maxes out at 3,000 and the roughness is pretty bad and starts at about 2900RPM and gets worse as the RPM increases. Also, pulling back so that the RPM is less than 2900 always gets rid of the roughness. ? So while the EGT profiles are essentially the same for both WOT situations, it would appear that when the engine is capable of going above 2900 RPM that the roughness occurs. ? Any thoughts? ? If interested, here are the two plot graphs for take-off and full power cruise: ? http://support.pcperfect.com/EGTs-TakeOff.pdf http://support.pcperfect.com/EGTs-WOT-Cruise.pdf ? Thanks!

List, On a similar note that don has observed, a month or so ago I was doing a touch and go when I inadvertently left the carb heat on. While making the climb out I noticed that the EGT's and CHT's had all evened out and looked the best that they ever had. I now wonder if it was warm air causing better atomization, or just the air intake system. Has any one else noticed this and if so what are you thoughts. David N601EX Jab3300 I appear to have an air intake issue. Flying without the air intake system and just the carb open to the cowling area and the plane flies extremely smooth. This fixed the roughness for everything except the last 1/4" of throttle travel. Repitching the prop so I had an in flight max of ~3300 RPM fixed the last 1/4" of roughness. Before the pitch change, my max out in straight and level was 3000 RPM. I'm going to be installing various modified air intake setups over the next few weeks and will post my results. For what it's worth, after re-pitching and flying without the air intake system, the plane is amazing. I've gained about 5 to 10 MPH in speed and 300 feet per minute or more in climb and the engine is much smoother in all RPM ranges. I'm really excited about getting a good intake system designed :) now that I'm seen the "other side" of this engine.

You're right, Lynn, apologies. Must be advancing years or British beer for the last couple of months that have taken their toll. Back in Brazil very soon with a healthier diet and more brain exercise, no doubt. There may well be others with the older couplers and the 'gap' who might be interested though.

Subject: Sonex Aircraft Responds to Peter Harris
From: Sonex Tech Support <tech(at)sonexaircraft.com>
Good Morning Jabiru Enthusiast, We at Sonex Aircraft LLC and AeroConversions LLC like to remain "hands-off" on the public lists but we do feel it is necessary to respond to Peter Harris (whose posting is copied at the bottom of this response) directly in this public forum. Specifically: Mr. Harris was supplied an AeroCarb which had an anodized aluminum slide with a thin delrin anti-friction gasket. He states he was supplied an Aerocarb with "no teflon liner". We have never offered a "teflon liner", though earlier AeroCarbs had teflon coated slides with no delrin gasket. Those were discontinued in favor of the anodized slide delrin gasket, which we continue to supply as standard equipment. His claims that we offer a teflon liner on the website are simply incorrect. He is perhaps confusing the delrin gasket with a "teflon slide". The outrigged throttle attachment performs well when properly installed. Proper installation is described in full detail in the AeroCarb's installation manual, including specific part numbers for rod ends, throttle cables, etc. Current AeroCarbs are shipped with an additional, alternative throttle connection which eliminates any chance of binding caused by improper installation, but requires a reversing throttle quadrant. Mr. Harris packed his AeroCarb with grease. Grease may be great on bulldozer tracks and railroad car couplers but has no place in an AeroCarb. We stand behind our products 100%. We asked Mr. Harris to return his AeroCarb for a free warranty inspection. He declined, stating it was "futile to return the carb unless you are willing to resolve the design issues". We asked for photos of his installation and they were never provided. Mr. Harris declined to accept the help we were offering and was clear he would not have been happy with any effort we would have made short of redesigning our product to his specific desires. Here is the full text of the final email sent (March 9, 2007) from the Sonex Aircraft tech support desk to Mr. Harris: ---Begin Hi Peter, We have more experience than anyone with the AeroCarb. Your binding is not normal which means there is an installation error or a defective part. We are asking you once more to return the carb for a warranty inspection, and to send us photos of your installation. Barring that we are unable to help you. If you you do not wish to take advantage of the warranty service/inspection of your AeroCarb, then we ask that you do not advise others on how to "fix" or install their AeroCarb, and when sharing your experience with others please be sure to tell them that we asked for the carb back for a warranty inspection and asked for photos to help diagnose your installation. We are not aware of any unresolved AeroCarb problems from customers who were willing to install the Aerocarb per our instructions and/or return their carb for inspection when problems occurred. We do know of people who have refused to work with us and have either given up on their Aerocarb, or have gone to great and unnecessary lengths to "fix" it. We stand behind our products 100%, for the safety of others, which is why we have repeatedly asked for photos of your installation and the return of your AeroCarb for inspection. ---End We have supported hundreds of AeroCarb installations on a wide variety of aircraft and engines. I have personally flown my AeroCarb-equipped Jabiru 3300-powered Sonex over 400 hours in the last 4.5 years. It bears repeating - no one has more experience with the AeroCarb than we do - and no one is more qualified than us to support our product. This will be our only post on the topic.

I was supplied with an Aerocarb with no Teflon liner. The slide worked on anodized metal to metal and jammed hard. The slide is pulled and pushed by an outrigged lever which causes the slide to twist and jam whenever pressure is applied. The attachment to cable is off centre and not even co planar with the slide. A Teflon liner is offered on the website but my several requests were ignored. I packed it with grease but it still jammed under the vacuum at low throttle settings and any attempt to quickly open throttle for a missed approach makes it jam harder because of the offset cable attachment. I attempted to discuss changes to the design but was abused. I have a copy of the correspondence. When I asked for a refund I was told to sell it on eBay. I would not have the conscience to give it away . Peter ________________________________________________________________________________

J The throttle quadrant does nothing to solve the basic design fault which is due to the cable attachment off centre and not co planar causing the slide to twist when moved, and the increased load due to friction on the slide when it is moved at low throttle settings. But it is not only the design issues but also the attitude of the CEO as he was not prepared to supply me with the Teflon insert listed on his web site and resorted to personal abuse when I suggested some design changes that would solve the problem. There have been engine failures and a forced landing due to jammed slides.

Specifically: Mr. Harris was supplied an AeroCarb which had an anodized aluminum slide with a thin delrin anti-friction gasket. He states he was supplied an Aerocarb with "no teflon liner". We have never offered a "teflon liner", though earlier AeroCarbs had teflon coated slides with no delrin gasket. Those were discontinued in favor of the anodized slide delrin gasket, which we continue to supply as standard equipment. His claims that we offer a teflon liner on the website are simply incorrect. He is perhaps confusing the delrin gasket with a "teflon slide". The outrigged throttle attachment performs well when properly installed. Proper installation is described in full detail in the AeroCarb's installation manual, including specific part numbers for rod ends, throttle cables, etc. Current AeroCarbs are shipped with an additional, alternative throttle connection which eliminates any chance of binding caused by improper installation, but requires a reversing throttle quadrant. Mr. Harris packed his AeroCarb with grease. Grease may be great on bulldozer tracks and railroad car couplers but has no place in an AeroCarb. We stand behind our products 100%. We asked Mr. Harris to return his AeroCarb for a free warranty inspection. He declined, stating it was "futile to return the carb unless you are willing to resolve the design issues". We asked for photos of his installation and they were never provided. Mr. Harris declined to accept the help we were offering and was clear he would not have been happy with any effort we would have made short of redesigning our product to his specific desires. Here is the full text of the final email sent (March 9, 2007) from the Sonex Aircraft tech support desk to Mr. Harris: ---Begin Hi Peter, We have more experience than anyone with the AeroCarb. Your binding is not normal which means there is an installation error or a defective part. We are asking you once more to return the carb for a warranty inspection, and to send us photos of your installation. Barring that we are unable to help you. If you you do not wish to take advantage of the warranty service/inspection of your AeroCarb, then we ask that you do not advise others on how to "fix" or install their AeroCarb, and when sharing your experience with others please be sure to tell them that we asked for the carb back for a warranty inspection and asked for photos to help diagnose your installation. We are not aware of any unresolved AeroCarb problems from customers who were willing to install the Aerocarb per our instructions and/or return their carb for inspection when problems occurred. We do know of people who have refused to work with us and have either given up on their Aerocarb, or have gone to great and unnecessary lengths to "fix" it. We stand behind our products 100%, for the safety of others, which is why we have repeatedly asked for photos of your installation and the return of your AeroCarb for inspection. ---End We have supported hundreds of AeroCarb installations on a wide variety of aircraft and engines. I have personally flown my AeroCarb-equipped Jabiru 3300-powered Sonex over 400 hours in the last 4.5 years. It bears repeating - no one has more experience with the AeroCarb than we do - and no one is more qualified than us to support our product. This will be our only post on the topic.

Subject: Sonex Aircraft Responds to Peter Harris
Date: Jan 18, 2009
Good evening Aerocarb enthusiasts. I suggest that this is not the place to conduct an Aerocarb argument and I will not be responding further except to correct the record. My carb slide was not coated with any product, it was anodized and ran on the Delrin gasket which however was fitted on one side only, and on the uncoated anodized surface of the frame on it's face. My contact with the supplier was based on preliminary bench testing when I reported the very high friction between these two uncoated anodized surfaces which were jamming due to the off centre action of the lever, and I requested the Teflon coated slide option offered on the website at the time. I made the request three times but was ignored. Then I used grease and found a big improvement in bench testing and so I completed the installation but subsequently the slide jammed when I started the engine. The cable installation was strictly according to Aerocarb instructions, but the off centre action of the carb lever assembly which is part of the product design, caused twisting and jamming at low throttle settings when there is significant pressure on the slide. >From the responses from the supplier I formed the opinion that Aerocarb were making very strong efforts to blame my installation for the issues even though my complaint and suggestions were based on bench testing and consequently I decided not to return it until the design issues were addressed. The response from Aerocarb below confirms that others have had similar problems with the product. When another operator at my field suffered jamming of his Teflon coated slide on late final (Sonex J2200) and was forced to recover with the adjustment of flap I decided that the carb was unsafe and requested a return for credit. I was refused warranty and told to sell it on eBay. Anyone who is curious to know what really happened may contact me direct (except for those on this site engaged in Aerocarb promotion) as I have a complete record of all of the correspondence. Qualified as an engineer I have given my informed opinion about what I consider to be basic design faults in the product which could be very easily fixed. You may like to inspect the product and decide for yourself. If you decide to use the Aerocarb I suggest that you make sure you have a slide that is coated preferably with Teflon on both sides and be very careful in operation at the lower throttle settings or with quick throttle movements. However based on my own experience I can only assume that the Teflon coated slide is no longer available.

Larry, The fuel pressure transducer should be placed between the engine fuel pump and the carb. Cap off the primer port on the gaslocator. Unfortunately I do not have a good picture of my fuel pressure transducer. Attached is the best I have. I mounted my oil recovery bottle on the right side motor mounts by way of sheet aluminum and adel clamps. I mounted the fuel pressure transducer to the back of this mounting sheet using a big adel clamp around the transducer.

I have a 3300 on the older 601HDS with a Dynon EMS (FlightDek 180) which should be similar to your setup. Since ultimately you care about the pressure that the carb is seeing, I took the fuel hose from the output of the mechanical/engine driven fuel pump and placed a T connector in it and connected one end to the fuel pressure sensor (that I got from Dynon) and the other end to the carb fuel intake port. My fuel pressure sensor is located on the right side of the firewall (passenger side). I also placed the fuel pressure sensor at the same level as the carb - I don't understand this but I was told that if I was concerned about the pressure #s of the carb, that the fuel pressure sensor should be at the same level for the best accuracy. Be aware that the Dynon setup may not be the best for the 3300s. If I remember correctly, our fuel pressure needs to be between 0.75 to 3 PSI. The Dynon is setup for a sender that measures 0 to 30PSI and combined with the fact that Dynon doesn't include a zero'ing function in their software to handle starting at a true 0 point with the sensor your numbers may not be all that accurate for the range we need to measure (with any luck they'll update their software in the next version). Also, if I understand this correctly the idea is just to have a bit of positive pressure with the Bing carbs. If you have too much - over 3 PSI (?), you'll overwhelm the carb and have issues with fuel overflowing, etc. For what it's worth, I normally see between 1 to 1.75 PSI with just the engine driven pump running depending on WOT or cruise.

Larry, I agree with Don that there could be something better than a 0-30 PSI transducer here. I asked Dynon about a smaller one last year, but they do not offer one. The 0-30 does seem to work OK, but we are definately on it's low end. If you could find a 0-10 or 0-15 transducer that works on 5 VDC excitation and is compatible with engine compartment surroundings, it would probably work.

Thanks Jrme! I went ahead and forwarded this information over to Dynon which is the EMS I'm using. I asked them to add support for it along with a zero'ing function. If anybody else would like them to add support for the 0 to 7 PSI UMA Sensor please e-mail them at support(at)dynonavionics.com (only if they see a decent number of e-mails will they add the feature, so please e-mail them if this affects you!). On the surface it appears to be a much better fit than the 0 to 30 PSI VDO (?) Sensor they are packaging now for the Jabiru Kits.

Hey Everyone, This is the response I got from Dynon on adding support for the lower pressure sensor for Jabiru Engines: >> I just talked to one of our engineers and he stated that we would consider adding a lower PSI sensor if there was enough demand in the market place to justify the Engineering time need to make the change...

Ian, I reported 18 months ago that the two assembly bolts which clamp and retain the starter were getting hot. The earth return is by means of these two bolts but they are set in Loctite and there is a voltage drop because of high resistance. I fitted a separate earth strap and got better performancxe from the starter.

Thanks Lynn, Jim and Peter for the information. Lynn, I can't see that you will ever run out of things to fiddle with :-) OK, so given that I need to add a strap to the starter, how do I get the bolts off without shearing them? I'm in contact with another builder of the same plane as me and he's just done this on his 2200. He tried heating the bolts to loosen the Loctite, but the bolts still sheared. Now, not only does he have to find some new bolts, he also has to take the casting to a specialist shop for them to remove the broken bolts. Any ideas? Again, many thanks for your responses.

Maybe I just got lucky, but in moving the ground wire for the starter, I didn't have any problems with the bolt and shearing, etc. I'd also recommend moving the ground wire or adding the strap for the starter. I was actually having issues with mine and moving the ground wire resolved the issue.

From: Richard Girard <aslsa.rng(at)gmail.com>
Chris, For small chips you can use the classic superglue and baking soda or microballons as fill. It's messy, but it will work for small stone chips and has the advantage of being instant. All you do is put a drop of superglue in the dent and pour in the baking soda or microballons as filler. If you cover with wax paper pulled tightly around the blade, there's almost no need for sanding. If it doesn't quite fill, just do it again.For slightly larger dents use JB Weld. Takes 24 hours to cure, and again use wax paper drawn tightly around the blade to shape the fill and minimize sanding. For large dents where there is a fair amount of damage to the carbon fiber it's probably a toss up whether to send the blade back to the USA for a fix or just buy another blade. I've used both these fixes on foam core, carbon fiber blades for my Powerfin prop. One, a superglue fix, has almost a hundred hours on it and is still solid.
