Is the float height ok? when the float is in the up position does the needle close against the seat cutting the supply of fuel from entering the fuel bowl? As explained before that is not a petcock it is a fuel pump. when the engine supplies vacume to the pump it pulls on the diaphram inside letting fuel flow from the tank.When you disconnect the fuel supply at the carb and turn over the engine if the fuel pulses out the pump is working properly. If the vacume supply line has fuel in it the pump is bad. You need to determine this with the pump first than make sure when the float rises it shuts off the supply of fuel to the carb cause if not the engine will flood. When you tore the carb down did you remove the float? Was the float installed correctly? TOM
