So I took my whizzer down local motor shop because I had past my knowlege of engines. The guy there fixed the timing and some other stuff, now it stays running and can go full speed on flat, but it doesn't have enough power to go up hills as the compression is 60-70 lbs.
Valves passed and air test so that leaves the cylinder. He mentioned there is a chance it could be fixed with new rings, but may also need to be bored out for a new piston and rings.
Motor still has a rattle from the crank or arm and only does it when motor has little or no resistance, such as coasting down a hill or when on a high idle. Flywheel seems to be spinning straight, it doesn't rub on the magneto if it is set close.
I have now spent around $1100 on just the engine alone and almost killed my desire to own it.
The question is, should I just buy the next professionally restored engine I come across and sell this one off for parts on ebay, take it to some one who can professionally rebuild it, or keep putting money into it until it runs? It is almost halfway though summer and won't have time to work on bikes when school starts.
