well me and my friend were looking at the engine and tring to figure out what is up with it. well i tried to spray carb claener down the carb in little squirts and it seemed to smoothe out but when i tried propane or mapp gas nothin.... i am tring to beleave it isn't a vac leak becuse i have seelant on every thing. so i think it is a leen out on the idle but on 3 carbs?
a another thing i am thinking is might it be that my timing set is off?
