i have checked the fuel level as discribed in this forum, level to or just above mating surface, have moved the tang up and down but still have a sputtering/running out of fuel like probelm in the 1/4 to 1/2 throttle, if i can feather the clutch or just rip it to get to the top end, it runs real strong, have tried all clip postions, still the same, have clean the jets/carbs no trash was found, all hoses are connected, boots look good, could it be a vacumn thing? what am I missing??? this is driving me crazy, short trip i know, but.......
