Can anyone say if the float tab on the end of the arm should face up or down? I took the fuel pump off to check the diaphragm and it only had a little rust on the engine side of the piston. It has to little check valves that pump and suck the fuel. When I took it off they fell out and I do not know the direction that they go back in. Can anyone tell me? The diaphragm looked good with no tears in it. I also tried to run the engine with gravity only and it would not run unless I put my hand over the intake to create vacuum. Otherwise there was no fuel flow through the filter. Tomorrow I going to move the fuel tank to a higher level and try the gravity plan again. I'm narrowing it down to two possibilities and they are the fuel pump and the float/needle valve connected to it. Any other ideas?
