I think I pushed her too hard....too early. Ive never had this before ever though. Time to throw in the spare engine I guess. I was wondering, do you think the crank shaft would be ok still, or should I just turf the whole lot....?
If that is a rear exhaust engine, the piston is modified completely wrong. Those cuts on the piston will not allow the engine to run properly. The exhaust side of the piston skirt must seal against the sleeve at TDC. What made you do that?
