I have a stumble between idle and WOT that I cant get rid of. Have cleaned the whole fuel system, replaced fuel tank, fuel hose and bulb, installed clear view fuel filter in fuel hose and pulled apart carb and cleaned well with carb cleaner and compressed air. Does anyone know what part of the carb would cause this. It runs good at idle and WOT but I have to rock the throttle to get it at WOT.
