[QUOTE="200racing, post: 321877, member: 5383"] 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. [url]https://www.**********/parts/search/Yamaha/Outboard/2000/C40TLRY/ELECTRICAL%201/parts.html[/url] 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 [/QUOTE]
