Good question Stan, I was basing that off of a post by someone earlier who said that Cliff R almost always advances Crower cams. I didn’t intend that it would be mandatory, but I guess I could have been more clear on that.
Either way I would degree the cam instead of just lining up the timing marks.
I would assume that the cranking compression on that side is due to the 65cc chambers and the decks possibly being machined. Indeed, that is a bit high for a pump gas engine.
Depending on what was discovered, the 65cc heads can be machined by Kauffman to have a larger chamber, but that would all need to be planned out before re-assembly.
