New member of the 'Sinker Club' (carb floats)

Do take the time to check these floats. I just checked 4 on an RV-12 that had all of them replaced late last year with the latest and greatest floats.

I weighed them yesterday and they were 10.6 and 8.5 grams respectively.

The customer did say the one side would intermittently overflow the carb.

Are you talking about Bing or MS?

Vic, how far reaching are reports of float problems?

I have no idea on that.

These are the floats on the 912 ULS.

Thanks for previous replies, - it seems that as well as sunk floats I had faulty, aged fuel. My situation & lifestyle sees me flying (or attempting to) only every few weeks or more. I had only 1/4 of a tank sitting for several weeks & after it was drained & refilled with Avgas 100LL the engine ran smoothly on the ground,- (unable to take it up due to inclement weather.) People here tell me that most schools with aircraft powered by Rotax 912 ULS engines use fresh BP95 Octane Mogas. Emphasis was placed on the fuel being FRESH. On my most recent attempt to get in the air I have discovered my fuel tank leaking from the level sensor plate on the front of the tank. When that new little problem is fixed I will try once again to commit Aviation. Cheers, DEAN
P.S, Mankind has sent men to the Moon, - how come we can't produce floats that float & continue to float??

Bing carbs are from Germany... I am part German myself. That country, despite great car design and huge profit margins, still hasn't sent a man to the moon.

Failure usually has to do with a sub contractor. Think Morton Thiokol, failed seals with liquid hydrogen, and the Challenger failure.

Bing Carbs got a new vendor for the floats, probably to cut costs. They are foam and don't seem to do so well as the previous vendors products. If we could find the name of the company that makes the floats for Bing Carbs, perhaps it could be addressed, the problem.

There are aftermarket parts from MS that are available, for half the price.

Seems like another type of floats have been issued; Part No.861189. Hopefully this will end this sad saga.. Cheers, DEAN

I've heard that before ...
