We "think" We found it.

So, we remove the bell housing, which unfortunatley means you have to drop the motor a bit, then run the car and see what's what. Nothing appears broken. So, we remove the clutch PP. And run the car again. This time with the exhaust off because we were getting lazy. Vibration is gone. So it must be the PP. we hope. I waiting for the new and different PP from Zoom. As opposed the the center force it had in there. I will take the fly wheel and pp to be balanced togther. If this does not work, I shoot myself.
