Answer
Hi Jack, He is somewhat correct. You might want to try this first, Pinch off the rubber fuel hose going to the fuel pump and run the engine until it stalls out. This might take a few minutes. Now remove the clamp from the rubber hose and start the engine, This might repair the problem. Sometimes dirt will get into the needle and seat keeping the fuel from shutting off.
