Jim, I think he is talking about the starter solenoid. It might have one of those where the power has to go through the solenoid out a terminal at the bottom to the switch for "power in".
Right, regarding the electrical issues. I was addressing the comments about having no fuel and needing to rebuild the carb. If it has a fuel shut-off solenoid and electrical issues, there might not be anything wrong with the carb, just no fuel flow due to the shut-off not having power.
