Default Re: Carburetor Float valves

This may or may not have been the problem with your float valves...

Any little speck if rust, dirt, etc., that flows down with the gas and gets trapped between the needle and the seat will cause the valve to leak (not shut off). Debris can actually get imbedded in the viton tip, making it not seal and also not flush out with gas flowing through the valve.

So it is a good idea to open the gas valve and flow some gas out of the fuel line (catch it in a clear glass so that you can see what's in the gas). Then connect the fuel line to the carburetor and go.

I hope this helps.
