I have a new fuel pump and a rejetted stock carb and the #2and#3 are really lean. I had a regular machine shop redo the head. Could it be the auiliary valve be messed up. I have 5 lbs of fuel . I need so help? I have when though 3 carbs and it still does the same back fies on the way up and down the rpm range.Thanks
