" I have put new diaphram,check vales, needle valve and gaskets in the fuel pump, disassembled and cleaned the carb. Now engine will start with choke but only run 5-15 seconds. Fuel line and primer bulb look good as well. Where do I go from here. Not sure what original settings on carb were, or which screws to play with. There is a needle valve just above carb throat (which one is this HI/Lo?) where is other adjustment screw. "
