ANSWER: Hi Douglas -

Have you checked the float system in the carb? I know you said it was cleaned, however the best way to clean a carb is to take it apart. Sometimes there is debris in the feed bowl and it gets into the valve that feeds gas into the bowl. This will cause the bowl to overflow into the intake manifold.

Hope this helps -

Answer
Hi Douglas,

I am not speaking of the fuel pump, but more of an internal issue in the carburetor. The only way that the carb would overflow with gas is if the float needle valve assembly is clogged or sediment is inside. This is inside the float bowl of the carb, so the carb has to be taken apart.

thanks
