stuck needle valve or bad float in carb.

SOURCE: gas leak out or the carburetor

Thiis usually caused by a failure of either the float valve or the float itself.

Bad float needle valve: If some dirt or other particle gets stuck on the needle valve or seat, the valve will not be able to completely close and fuel will continue to flow into the bowl and eventually overflow. A new needle valve and seat are < $5.00 on-line.

Bad float: If the circular float gets a hole in it, fuel will get inside and the "float" will get heavy and no longer float on top of the fuel in the bowl. Because it doesn't float it will not rise high enough to push the needle up into the seat and keep extra fuel from entering the bowl. A new circular float is < $10 on-line.
