thanks other brother earl, & earl, I re measured the stroke, I think I was a bit long.

I come up with a nice 30cc, which makes sense to me.

I'm gonna put the zinger pusher prop on it, wondering what would be best for this engine? does an 18x6 or 8 make sense? Or does the 16x10 three blade work out?

I think I'm gonna chuck up some hex steel in the lathe this afternoon, and thread the inside to go on the crank.
Wondering if anyone has used some sort of keeper system to keep the prop shaft from coming unthreaded when idling down?
I was thinking of a hex screw, or possibly drilling through both prop shaft and crankshaft and using a keeper pin?

thanks again.
