Hi All, 

 For what its worth, I though I`d share a recent  problem & solution with a Bing carb I had this week. It all started last  Sat, when after a short flight in my MK3C 912 bird, one of my bing 64 carbs  started leaking after engine shutdown. It quit after a minute or so, but not  after scaring the bejeebers out of me, cuz the fuel was boiling off of a hot  exhaust pipe!

 Once it quit, & cooled down for a few miute, I  thought, I`d better be sure where it was coming from. I turned on the electric  fuel pump & the carb bowl instantly was wet & dripping  again.

 Since it was hot outside, & in the hangar,  & the engine was still hot, I left the airport ticked off, thinking I`d  research the possible problems & check out solutions.

 Not knowing that much about bing 64s, I asked a few  of my fellow Kolb drivers their opinions, and, once I learned more, Agreed that  it must be a sticking float needle & or float bowl gasket.

 Didn`t get to get back to it until Tuesday, &  had a helper flip on the fuel pump again & after repeated checks, found that  it was the Brass fitting that the fuel line attached to! This wasn`t a threaded  in fitting like on the new carbs, but a "pressed in fitting" (Pressed in  according to the folks at BING in Kansas) 

 LOOOONg story short, (I know, too late, its already  long), the folks at Bing, L. E. A. F.  & Lockwood, have never seen this  before & each had a different recommendation. The bottom line was this, that  fitting was not just pressed in, but was inserted with an "O"-ring. The O-ring  was letting fuel pass by. Once I got the fitting out, found that it was a Nickel  fix, re-inserted it a new o-ring  with some green Locktite ( LEAF  Recommended), I enjoyed a 15 minute check flight yesterday, & 1.2 hours  today.

 I also bought the fuel drip pan kit from CPS &  will install it shortly .

 Some of you may have already known  of this  O-ring deal before, but Since Bing & LEAF & Lockwood didn`t, I thought I  `d pass it along.The folks with thread-in fittings have an advantage, cuz the  seal will be easier to replace.

How did you get it out without destroying it?…  was it loose, or did it take a bit of twisting and pulling?   What kind of o ring did you use?  All orings are not made of the same material,   was what you used suitable for use with gas?

Boy I hope it`s compatable with gas, now you`ve  prompted me to do some more research on the other ones in this o-ring stash that  it came from.I got it out by having a helper securly hold the carb on a work  bench, & I put a short pc of fuel line over the nipple to cushion &  protect it. Then held it just below the flare with a unique pair of pliers that  when clamped, held close to the same diameter as the pipe nipple, & tapped  the Pliers with the hammer, away from the carb body, & after a few Raps, it  popped out.

 now on to research to make sure I put a gas  compatable o-ring on it. If not, I gotta do it again, thanks for the heads up on  the o-rings.

Here is a fluid compatibility guide for o-ring materials that may help you.

Thanks for the chart, they are NBR & according  to this chart, they are recommended for gasoline.  Jim

Glad to help.



On a related subject, according to this material compatibility chart, the Viton tips on the float valves in Bing 64 carbs on 912 engines is rated only Marginal for Ethyl Alcohol. So those of us flying with 912 engines should keep close eye on these valves if we are running ethanol laced autogas.

great.... and here I was thinking Rotax approved 10% with no restrictions including the carburettors.



I'd take that to mean the carburettor parts should still last their normal lifetimes, but we can't let the maintenance slip as long as before .



FWIW, I'm on my 3rd tank (maybe 4th) of 10% premium with no running problems or problems with the fuel system. So far no vapour lock or even so much as a burp even up to about 9000'. I guess it'll be years from now before I could find out about any corrosion problems or shortened lifetimes of carburettor rubbers.



Time to order my carburettor overhaul kits anyway....
