i have eliminated the fuel system. my carbs are spotless. running from a hanging bottle and catching the gas out of the pump it supplies i nice stream that more than matches what the engine is burning.


 i had a friend who is a mechanic come over and look at it. we went through the electrical system. once it got warm it started its run and cut off routine we unplugged a thermal censor and it would run much better not perfect but better. part #12 on this diagram.

seems like more than coincidence to me but i want to be sure.

using the ohm feature on a voltmeter you can tell when it gets warm it completes a circuit.


does anyone know what temp this circuit is supposed to operate at?

its part # 6H4-82560-00-00
