This engine has unfortunately been highly polished by the previous owner. The head gasket is in two parts. but the broken one could be used as a template for a new one. The backplate of the motor has been over tightened at some point and there is a hole in the backplate where the tank screw should screwin. There is a spark plug, although I have not tested it. Needle valve and points seem intact. The points adjustment lever is there. I have never run this motor.
