Lynn,
  I attended the Lockwood school in Jan. We tore a carb completely apart and 
reassembled it as part of the school. The diaphragm is normally replaced do to

time on the rubber part.(unless damaged of course) I replaced my diaphragms 
when I returned home from the school. The old ones appeared fine so I really 
doubt they needed it. I remember from the class that it is really easy to get 
the cast rubber protrusion on the diaphragm out of alignment with the 
corresponding slot in the carb casting. You have to hold it in the slot with your
thumb 
while you assemble the two halves. The diaphragm is NOT glued down in any 
fashion.
  I don't know if this relates to your problem but you might check, if you 
have to disassemble them. I know I replaced the needles (again do the time on 
the rubber tips) and ended up going back to the originals because of fuel 
spitting out of the intakes.(springs too strong on the new needles I think)
  Please let us know what the problem was when you find it!

I'll let you know, Dick. Right now I'm replacing fuel lines firewall  
forward, and checking fuel flow before and after.
Yes, I see how that diaphragm could get out of the slot. I've had the  
carb home here while I watched the race yesterday, just tinkering  
with it and reading the Big manual. I'm gonna gt real well acquainted  
with it before this problem is over. I'm also gonna try one of my old  
float needles, just to try something else.

The Jabiru uses a CV carb, a 40mm, and sells the manual for aircraft  
carbs, so they must know that they are being used. Or is it just the  
64's that should not be used? No matter, they are sold to Jabiru as  
an aircraft carb, and Rotax uses them as well...maybe not the 40mm,  
but a CV carb just the same. Of course, the lawyers will deny that  
they approve any part for aircraft use.

Lynn,
  Question:  Is the carb you use the same as on a 64 used on the Rotax 912UL? I
have not researched this.
If so, you could install one, or both, of mine for trouble shooting purposes. I
don't anticipate flying much for a while....got some jobs to do.
About  80 hrs TT and working fine.
It would require a drive to Howell (OZW) airport, but you're a travlin' man.

mid range has been the most challenging part of tuning the bings for me.  have
you tried raising the needle/lowering the circlip?

installing the R3600 in a Hatz Classic.  almost done with the rough plumbing and
wiring so I can drop the engine and cover the fuselage.  I figure it will take
about a year to finish up.

mid range has been the most challenging part of tuning the bings for me.  have you tried raising the needle/lowering the circlip?
 
installing the R3600 in a Hatz Classic.  almost done with the rough plumbing and wiring so I can drop the engine and cover the fuselage.  I figure it will take about a year to finish up.

________________________________ Message 10 ____________________________________ Time: 10:51:17 AM PST US From: Lynn Matteson Subject: Re: Kitfox-List: Re: Bing carbs For some reason the Jabiru mods to the carb include using a "proprietary" needle, using just one groove. Later Service Bulletins have you installing a 2-groove needle which is fatter at the top (low range and idle) and a larger needle jet, to control EGT's a little better. I'm thinkin' positive that I will reinstall carb, light it up and it'll be ready to fly! Perhaps God has different ideas though, because it's foggier than hell here today. : ) Lynn Matteson Grass Lake, Michigan Kitfox IV Speedster w/Jabiru 2200 flying w/480+ hrs/down for annual do not archive On Mar 31, 2008, at 11:20 AM, kerrjohna@comcast.net wrote: > mid range has been the most challenging part of tuning the bings > for me. have you tried raising the needle/lowering the circlip? > > installing the R3600 in a Hatz Classic. almost done with the rough > plumbing and wiring so I can drop the engine and cover the > fuselage.

My carb ( a 94 CV) is the constant depression (does this describe the way people feel who work on the damn things?) carb, also known as a CV...don't ask me why, and the person I talked to at Bing didn't know the connection. Suffice it to say that constant velocity and constant depression mean the same thing to Bing. I got some good feedback from Bing, including the diagnosis that my diaphragm is probably ok, and there is no test, as I had hoped, to tell whether or not it was good other than a visual, and that it did not "flop all over the place." So I'm putting it back together, changing some fuel lines, and if all goes well I'll report what I did.

Or a least 99% certain of success. I haven't flown it yet, but it looks promising. I ran it up after the fix, and it was a marked improvement....I tried to force the throttle open quicker than normal and it hesitated a bit but took the bait. It no longer just quits. I was pushing it a bit quicker than normal, which was not a fair test, but it was taking it. Now for the cure....it seemed to be between two things....low float level, maybe the wrong float needle. I had changed the float needle and seat back in Dec., and had told Bing to send me the correct needle for the 2.5 mm seat, and they sent me the light-springed version. They are available in light, medium and heavy springs. The light one worked right up until last week when I changed to the 2.78 mm needle jet, and that's where all this nonsense began. When I changed back to the 2.76 mm needle jet, it still quit during mid- range, so something had to be wrong other than the needle jets. Then I started to change things. I changed float level and that didn't help. What finally worked was going back to the medium spring on the float needle, and setting the float level absolutely parallel to the carb base...I had it much too low, but in my defense, I was setting it by opening the fuel flow, and raising the float to shut off the flow and noting the position of the float...this was with the carb on the plane. Today, with the carb off the plane and inverted, I set the float to be parallel to the base with the medium-spring needle, and that's what worked. The real proof will come tomorrow, if the weather is good enough for a flight. Thanks for all the input, guys and gals. Like it says in the manual, try one thing at a time or you won't know what cured the problem. If I could accept that philosophy, I might make a better mechanic, after being one for all these years. : ) Lynn Matteson Grass Lake, Michigan Kitfox IV Speedster w/Jabiru 2200 flying w/480+ hrs/down for annual ________________________________ Message 17 ____________________________________ Time: 02:15:20 PM PST US Subject: Kitfox-List: Re: Wanted Starting motor From: "dave" > john beirne > > > > Joined: 02 Oct 2006 > Posts: 16 > Location: Ireland > Posted: Fri Mar 28, 2008 4:11 pm Post subject: Re: Wanted Starting motor > > -------------------------------------------------------------------------------- > > Hi > I have just purchased a starter from this company. it is identical to the one removed. > > http://www.db-starter-alternator.com/Items/ws1?&caSKU=ws1&caTitle=100%25%20NEW%20Seadoo%20Starter%20580%20650%20GTS%20GTX%20SP%20SPX%20XP%20WS1 > John, Have you tried this starter yet ? looks like it rotates CCW , Rotax requires Clockwise.

The Pre IV models have a steeper windshield and I would stick to .060 to .080 " lexan. It won't crack if you treat it right. Cutting with tin snips works but you fracture the edges and MUST clean them up or cracks can propagate from the edges and especially at the top where the windshield bends around in a complex bend. you can use a hand plane to true up the straight edges and take of the sharps edges.
