I had the engine rebuilt last year and the carbs rebuilt it runs like a scalded dog but when i stop and try to take off it is flooded and i have to take the cover off and let it run with the idle raised up high to burn off the extra gas i foul out plugs every other trip out the oil injection has been removed I am mixing the fuel right it is only one or two cylinders flooding I checked the floas and the function right!! what could my problem be?
