I've got to suspect the float or its valve. The float could be sinking. There could be a problem with the float valve seat where it can't seal in certain positions. Good Luck, Rick
Yeah, I am thinking the same thing. Maybe a pin hole in the float? It slowly fills up with gas and no longer floats?
I ordered the carb, so I should know soon.
