    Someone has replaced the original stop switch with that hokey set up, might be a problem.  The original wiring had connector plugs that would allow you to disconnect the stop switch from outside the mag plate.  If so, I would try running the engine with that stop switch unplugged.  Unfortunately, it looks as if whoever was messing with this engine removed the plugs as well.

    You mention the engine starts right back up again when it stalls.  Will it start without pumping up the fuel bulb again?  If so, the fuel pump is probably not the issue.  Does the engine sneeze/cough when it stalls, or just shut off?
