MC5 400 Carburetors

Rebuilding the Bing is definity worth rebuiding, I relaced all of the jets and the slide. but I also replaced all the o rings and gaskets... It made a huge difference... I have been playing with the idea a having the slide coated, it could be coated to build it back to stock specs or if the body was really bad, maybe it could be cleaned up and then the slide coated.. This would not only solve the problem but also eliminate futher problems with the slide...

Maybe the float needle is bad.  They come in either hard or soft.

I have a 1978 400, and I found my cylinder base gasket was leaking causing my idle to be erractic.

*UPDATE*

Stripped the carb, give it a good clean, the floats aren't sticking, nor do they appear to high, however, the slide has a large amount of wear in one area.

I have ordered a new slide off andre (ktm klassiker), for only 36 euros! I contacted the Bing Agency, they wanted $140 JUST for a slide! $460 for a carb :|
