New to scene, have just inherited "Mig 21"
I've inherited a nearly unused "Mig 21" Russian bike engine. It's locked up, but removing the cylinder revealed a nearly perfect cylinder and piston. I think the problem is an accumulation of rusty grease at the junction of the small gear connected to the connecting rod and the large gear which is the transmission. I'd like to remove the small gear to free up the shaft but can't get it off. The rest of the motor looks to be in fine shape. I'd also like to obtain a new lighting coil as it measures an "open circuit" and new gaskets. Anyone with experience with this very neat little engine, I'm ALL EARS!
