E50BELCOB top carb spitting fuel after carb rebuild/cleaning. my top carburetor is spitting a tiny constant stream of fuel. I haven't had the motor for very long, and replaced the main carb gaskets and cleaned the carbs with carb cleaner and jets with a violin string. this carb does not adjust idle in this orifice, it is just a plug with a hole. I don't know if it just started doing this b/c I just started running it and watching it run with the silencer off. When I got the motor, I converted to premix by adding the fuel pump to the side of the crank case everything else seems to be working fine, looks pretty good too. Maybe too much fuel pressure? I checked the floats by adjusting them as stated here, and then blowing into the fuel inlet and turning them upside down, and the needle valves seem to be fine. I have searched around here but haven't seen anyone else with this problem. and help/ links would be appreciated. Thanks.
