I finally got a chance to pull the jug and take some measurements. The bore is 1.42" and the stroke is 1.26" which are the exact measurements of the Duropower 32.6cc engine. I am not going to worry about ccing it, I will just go off of these measurements.
The piston, rings and cylinder look great. Hopefully my lathe will be here in a few days and I can cut down the flywheel and use it for the pickup ring. Does anyone know of a bigger carb that will bolt up to this engine.
