I have a Mikuni carb on a Cuyuna UL202 with a single squeeze bulb primer with the loop around and a one way check valve so I don't have to pinch to prime. Upon squeezing the bulb it is very hard to get fuel into the carb in any amount ...kind of dribbles through slowly... after squeezing for a while , I can get it started usually on the 3rd pull but then the piston enrichment needs to be used numerous times till it runs at 3,000 for a while and the fuel lines fill up. It seems as though I can't get anything through the single fuel pump in any amount ....but the pump works when the engine is running...if I restart within an hour I have no problem at all with air in the lines. Is this normal because of the check valves in the fuel pump ? The engine runs strong and temps are ok in flight ..... both EGT's at 1125 except for a CHT spread of 350 and 270....I suspect a leaking inlet carb needle but the inability to prime has got me wondering if I may have 2 problems...maybe a new pump diaphram ? I think the piston enrichment is ok ! Too much fuel may have been the reason why I had a carbon problem a short while ago but a slow leak in my inlet needle should not be a problem except at idle....????

Thanks Steve ________________________________ Message 7 _____________________________________ Time: 06:38:07 AM PST US From: "PATRICK LADD" Subject: Kolb-List: check ride --> Kolb-List message posted by: "PATRICK LADD" Hi all, the following was sent to me by a mate in OZ. Enjoy Dear Pat: I hope you and the family are well. I know it's been quite a while since you last heard from me, but Doreen and the rest of the family are all OK but I think they're getting a bit pissed off with station life, particularly when there's bugger all rain to speak of - and the cattle and sheep are dying all over the place! I'm writing to you, mate, because I need your help to get me bloody pilots license back (you keep telling me you got all the right contacts, well now's your chance to make something happen for me because, mate, I'm bloody desperate). But first, I'd better tell you what happened during my last flight review with the CASA Examiner. On the phone, Ron (that's the CASA d!ckhead) seemed a reasonable sort of bloke. He politely reminded me of the need to do a flight review every two years. He even offered to drive out, have look over my property and let me operate from my own ALA. Naturally I agreed to that. Anyway, Ron turned up last Wednesday. First up, he said he was a bit surprised to see the plane outside my homestead because the ALA is about a mile away. I explained that because the strip was so close to the homestead, it was more convenient than the ALA, despite the power lines crossing about midway down the strip (it's really not a problem to land and take-off because at the half-way point down the strip you're usually still on the ground). For some reason Ron seemed nervous. So, although I had done the pre-flight inspection only four days earlier, I decided to do it all over again. Because the pr!ck was watching me carefully, I walked around the plane three times instead of my usual two. My effort was rewarded because the colour finally returned to Ron's cheeks - in fact they went a bright red. In view of Ron's obviously better mood, I told him I was going to combine the test flight with farm work as I had to deliver three poddy calves from the home paddock to the main herd. After a bit of a chase I finally caught the calves and threw them into the back of the ol' 172. We climbed aboard but Ron started getting' into me about weight and balance calculations and all that bullsh!t. Of course I knew that sort of thing was a waste of time because, calves like to move around a bit, particularly when they see themselves 500 feet off the ground! So, it's bloody pointless trying to secure them as you know. However, I did tell Ron that he shouldn't worry as I always keep the trim wheel 'Araldited' to neutral to ensure we remain pretty stable at all stages throughout the flight. Anyway, I started the engine and cleverly minimised the warm-up time by tramping hard on the brakes and gunning her to 2,500rpm. I then discovered that Ron has very acute hearing, even though he was wearing a bloody headset. Through all that noise he detected a metallic rattle and demanded I account for it. Actually it began about a month ago and was caused by a screwdriver that fell down a hole in the floor and lodged in the fuel selector mechanism. The selector can't be moved now, but it doesn't matter because it's jammed on 'All Tanks', so I suppose that's OK. However, as Ron was obviously a real nit-picker, I blamed the noise on vibration from a stainless steel thermos flask, which I keep in a beaut little possie between the windshield and the magnetic compass. My explanation seemed to relax Ron because he slumped back in the seat and kept looking up at the cockpit roof. I released the brakes to taxi out but unfortunately the plane gave a leap and spun to the right, "Hell" I thought, "not the starboard wheel chock again". The bump jolted Ron back to full alertness. He looked wildly around just in time to see a rock thrown by the prop wash disappear completely through the windscreen of his brand new Commodore. "Sh!t, now I'm really in trouble", I thought. While Ron was busy ranting about his car, I ignored his requirement that we taxi to the ALA and instead took off under the power lines. Ron didn't say a word, at least not until the engine started coughing right at the lift off point, then he bloody screamed his head off, "Oh God! Oh God! Oh God!" "Now take it easy, Ron" I told him firmly, "that often happens on take-off and there is a good reason for it." I explained patiently that I usually run the plane on standard MOGAS, but one day I accidentally put in a gallon or two of kerosene. To compensate for the low octane of the kerosene, I siphoned in a few gallons off super MOGAS and shook the wings up and down a few times to mix it up. Since then, the engine has been coughing a bit but in general it works just fine, if you know how to coax it properly. Anyway Andy, at this stage Ron seemed to lose all interest in my flight test. He pulled out some rosary beads, closed his eyes and became lost in prayer (I didn't think anyone was a Catholic these days). I selected some nice music on the HF radio to help him relax. Meanwhile I climbed to my normal cruising altitude of 10,500 feet (I don't normally put in a flight plan or get the weather because as you know getting NAIPS access out here is a f#*% joke and the bloody weather is always 8/8 blue anyway. But since I had that near miss with the Saab340, I might have to change me thinking). Anyhow, on levelling out I noticed some wild camels heading into my improved pasture. I hate camels and always carry a loaded .303 clipped inside the door of the Cessna just in case I see any of the bastards. We were too high to hit them, but as a matter of principle, I decided to have a go through the open window. Mate, when I pulled the bloody rifle out, the effect on Ron was friggin' electric. As I fired the first shot his neck lengthened by about six inches and his eyes bulged like a rabbit with myxo. He really looked as if he had been jabbed with an electric cattle prod on full power. In fact, Ron's reaction was so distracting that I lost concentration for a second and the next shot went straight through the port tyre. Ron was a bit upset about the shooting (probably one of those pinko animal lovers I guess) so I decided not to tell him about our little problem with the tyre. Shortly afterwards I located the main herd and decided to do my fighter pilot trick. Ron had gone back to praying when, in one smooth sequence, I pulled on full flap, cut the power and started a sideslip from 10,500 feet down to 500 feet at 130 knots indicated (the last time I looked anyway) and the little needle rushing up to the red area on me ASI. Sh!t, what a buzz, mate! About half way through the descent I looked back in the cabin to see the calves gracefully suspended in mid air and mooing like crazy. I was going to comment on this unusual sight but Ron looked a bit green and had rolled himself into the foetal position and was screamin' his f*&%# head off. Mate, talk about being in a bloody zoo. You should've been there, it was so bloody funny! At about 500 feet I levelled out, but for some reason we continued sinking. When we reached 50 feet I applied full power but nothin' happened; no noise no nothin'. Then, luckily, I heard me instructor's voice in me head saying "carby heat, carby heat", so I pulled carby heat on and that helped quite a lot, with the engine finally regaining full power. Whew, that was really close, let me tell you! Then mate, you'll never guess what happened next! As luck would have it, at that height we flew into a massive dust cloud caused by the cattle and suddenly went I.F. bloody R, mate. Andy, you would've been bloody proud of me as I didn't panic once, not once, but I did make a mental note to consider an instrument rating as soon as me gyro is repaired (something I've been meaning to do for a while now). Suddenly Ron's elongated neck and bulging eyes reappeared. His mouth opened wide, very wide, but no sound emerged. "Take it easy," I told him. "We'll be out of this in a minute." Sure enough, about a minute later we emerge; still straight and level and still at 50 feet. Admittedly I was surprised to notice that we were upside down, and I kept thinking to myself "Sh!t I hope Ron didn't notice that I had forgotten to set the QNH when we were taxiing". This minor tribulation forced me to fly to a nearby valley in which I had to do a half roll to get upright again. By now the main herd had divided into two groups leaving a narrow strip between them. "Ah!" I thought, "There's an omen. We'll land right there." Knowing that the tyre problem demanded a slow approach, I flew a couple of steep turns with full flap. Soon the stall warning horn was blaring so loud in me ear that I cut its circuit breaker to shut it up, but by then I knew we were slow enough anyway. I turned steeply onto a 75 foot final and put her down with a real thud. Strangely enough, I had always thought you could only ground loop in a tail dragger but, as usual, I was proved wrong again! Halfway through our third loop Ron at last recovered his sense of humour. Talk about laugh. I've never seen the likes of it; he couldn't stop. We finally rolled to a halt and I released the calves, who bolted out of the aircraft like there was no tomorrow. I then began picking clumps of dry grass. Between gut wrenching fits of laughter Ron asked what I was doing. I explained that we had to stuff the port tyre with grass so we could fly back to the homestead. It was then that Ron really lost the plot and started running away from the aircraft. Can you believe it? The last time I saw him he was off into the distance, arms flailing in the air and still shrieking with laughter. I later heard that he had been confined to a psychiatric institution - poor bastard! Anyhow, mate, that's enough about Ron. The problem is I just got a letter from CASA withdrawing, as they put it, 'my privileges to fly'; until I have undergone a complete pilot training course again and undertaken another flight proficiency test. Now I admit that I made a mistake in taxiing over the wheel chock and not setting the QNH using strip elevation, but I can't see what else I did that was so bloody bad that they have to withdraw me flamin' licence. Can you? Anyhow mate, the reason for writing to you is to ask if you know any flight instructors who would be willing to come out the station for about 2 months to help get me back up to speed. I'll pay them good money while they're here and they won't have to worry about paying for food or accommodation. Looking forward to your response. Until then, take care, mate.

Sorry I didn't make that as clear as I could have.... They claimed that if the idle rpm and idle jetting were properly set up (down around 2100 someplace), and the enrichment piston is in good repair, then the primer pump is not necessary to crank the engine. They also said that if one really wanted to keep the primer pump, it was a good idea to replace it at least every year or 18 months, since the problems were associated with older pumps and new ones are cheap.... under $10. Their logic for removal is that if it is not required, the pump and its one-eighth inch lines become just unnecessary points of potential failure on the engine.... get rid of it. Folks, I agree with the Sebring gents on this one. I've never had a primer on my 447.... just the in-line squeeze bulb with bypass. I pump the fuel lines and carb bowl full with the squeeze bulb, open the enrichment valve full, give it two pulls with ignition off, then one pull with live ignition and 9 out of 10 times it's running. I've flown here in Tucson when it was in the 20's at the airport and in Bryce Canyon it was 30 and never noticed any difference in starting from when it's 70. If you have good clean fresh fuel, good plugs, fill the fuel lines and carb bowl, your enrichment valve is working properly and your idle jet is set properly you shouldn't need a primer to start it easily. Maybe someone in MN or Maine might need a primer if they are flying when it's zero or below... When mine no longer does this, I'll be taking everything apart until I find out why.

Beauford/All, I took a look at the black auto fuel lines on the float plane and after 5 months of exposure to mixgas they looked ok on the inside. This was a gates brand. I did wander out to my shed where I keep all of my now unused boat and fishing gear and inspected an old outboard primer bulb fuel line combo for my trusty 30 hp Johnson. after years of abuse and neglect it still looked good. It was made from Trident # 309 hose that meets SAE J1527 USCG & ISO 8460 Type B1 standards for outboard use. This stuff does not cost any more than Auto line or even Tygon. I think I will give it a try.

After a couple of folks mentioned it offline, one thing I guess I should put out on the wire is additional evidence that the carb enrichment piston played a role in the carbon problem... I previously mentioned that the mechanics discovered the bottom insert (rubber) in the piston was pushed up and permanently deformed away from the valve seat. They speculated that this could have been leaking raw gas into the carb circuit. The enrichment piston was replaced. The one hour and six minutes I flew it yesterday consumed just slightly less than 2.5 gallons... and most of that was hard running, up around 5900 to 6000, with occasional 3 minute bursts at 6500 or 6600. Before, it would have easily used over 3 gallons for an hour of average cruising around... more like 3.3 to 3.4. That gas was going somewhere, and based on the reduced fuel burn rate yesterday, I strongly suspect it was passing through the defective seat in that piston and going directly into coke production. Henceforth, I plan to yank that little item out and have a look at it on an annual basis... Before, all I ever inspected was to make certain that I could feel the piston hit bottom when I closed it. Obviously, that was not adequate. Will attempt to fly it again this afternoon, weather permitting... will measure fuel burn again.

If the 1/4" primer line ever comes loose (which has never happened in 18 years of flying these things), it will only let a small amount of air into the carb when compared to the rest of the volume of air coming through the air cleaner. This would not cause a seizure, just a high EGT reading. For you pilots living in the north country, try starting a 2-stroke Rotax below freezing with just the enrichner (choke) alone. A primer will start the engine on the very first pull if it's done properly. At least mine does. Which would you rather have?

They claimed that if the idle rpm and idle jetting were properly set up (down around 2100 someplace), and the enrichment piston is in good repair, then the primer pump is not necessary to crank the engine. They also said that if one really wanted to keep the primer pump, it was a good idea to replace it at least every year or 18 months, since the problems were associated with older pumps and new ones are cheap.... under $10. Their logic for removal is that if it is not required, the pump and its one-eighth inch lines become just unnecessary points of potential failure on the engine.... get rid of it. Folks, I agree with the Sebring gents on this one. I've never had a primer on my 447.... just the in-line squeeze bulb with bypass. I pump the fuel lines and carb bowl full with the squeeze bulb, open the enrichment valve full, give it two pulls with ignition off, then one pull with live ignition and 9 out of 10 times it's running. I've flown here in Tucson when it was in the 20's at the airport and in Bryce Canyon it was 30 and never noticed any difference in starting from when it's 70. If you have good clean fresh fuel, good plugs, fill the fuel lines and carb bowl, your enrichment valve is working properly and your idle jet is set properly you shouldn't need a primer to start it easily. Maybe someone in MN or Maine might need a primer if they are flying when it's zero or below... When mine no longer does this, I'll be taking everything apart until I find out why. Jim Hefner Tucson FF#022 Jim and others, Think about it, if the enrichner fails then it really does a number on your engine (just ask Beauford). If the 1/4" primer line ever comes loose (which has never happened in 18 years of flying these things), it will only let a small amount of air into the carb when compared to the rest of the volume of air comingthrough the air cleaner. This would not cause a seizure, just a high EGT reading. For you pilots living in the north country, try starting a 2-stroke Rotax below freezing with just the enrichner (choke) alone. A primer will start the engine on the very first pull if it's done properly. At least mine does. Which would you rather have?
