OK Boy and girls, i am just about ready to throw my JP in the bin. I have rebuilt the carby, tried a different carby and i still cant get a tune on this engine. It a JP FX3 Full option, it wont idle properly, i cant get it to rev or pull out of a corner and last night, it went from running at 70 degrees C in warm up to 233 deg C at the end of a 6 minute race has anyone got any ideas?

Cheers Daniel
