I NEED FLOAT LEVEL MEASURMENTS ASAP

[Bense]

I'm dripping fuel, hard to start. I had the carbs apart and cleaned them well. Put it all back together and same thing. Plugs are wet. Taking them apart again to check needle and seat but anyone know the stock carb float measurement. I know to turn it upside down and measure. THanks

 

Oh and yes my chocke tube is in place. :biggrin:

21mm from the top of the float (upside down) to the base of the gasket surface (no gasket)...

Remember, the needles have springs in them for riding over bumps...be sure you're not pushing the floats too hard.

 

But...I just eyeball 'em...level.

 

I bet you got a spec of dirt on the needle or seat....

Thank you much. I am going to head out and measure them.

Last weekend I was dropping a cylinder, and I think its due to this problem fouling a plug.

Alright here is the deal. I have had the carbs in and out 5 times tonight. Its not a grain of sand, something has to be a little tweaked on the float. Its flowing out of the left (choke side) carb. My buddy came over that is motorcycle mechanic and was looking at it as well. He also can't figure out whats up.

 

I think I am going to go out, pull the carbs off again. Pull the float off the right carb, and put it on the left carb and see if that seals it. If it does, then I need a float. If not, then who the fock knows. We even pulled the needle apart and the spring is working like is should. We thought maybe a hole in the float making it heavy and not shutting it off, but thats not the case either. I build drag boats and very mechnical and this one has me stumped, if this was a big block chevy I wouldn't have this problem. Off to troubleshoot more. Anyone has any ideas feel free to toss them my way. Thanks.

 

Oh yeah they measure 21mm or very close with the gasket off.

So after putting the right float (only) in the left carb, it doesn't leak. I kept the left needle and seat in the left carb, just installed the float as a test.

 

NOW anyone know what these run? Calling my yamaha dealership tomorrow.
