I moved the servo back. Replaced the metal rod with plastic. Placed rubber gromets between motor mount and fire wall. Rapped the receiver in more foam. The problem got about 75% better but still there. So I replaced the receiver with a PCM receiver and the problem completly disappered. I flew the plane with no noted problems what so ever. It flew and ran perfect. Enough power to hang on the prop at 75% throttle. The PCM may have covered the problem up but it flew perfect. So if that is the case then oh-well. I have tryed everything else with the exception of changing the ignition and that would defeat the purpose of placing a converted chain saw engine in it(cheaper).

Thanks to all for your help
