Great job greg r, also the egg shape are you talking about the center end of the shaft ? It supposed to have a convex radius (small radius for the ball to center in). I would look into fixing the engine before running it anymore at all, it might be a lot cheaper if you can scrounge some parts before anything starts making contact inside the motor.

The flex members were pretty well stretched too.
The bad news is the engine has a really bad knock, I thought just maybe the wobbling drive shaft might have something to do with it.
On to another thread.
