Sixties cars with rubber isolated harmonic balancers were notorious for slipping the outside wheel. That left the timing marks pretty worthless. Using just basic tools you can check your timing marks. A drinking straw is about a cheap a tool as you are going to use to find TDC on just about any motor. That will give you a good start without a Geometry lesson. Sounds like you are just about there. I can almost hear that engine starting. Mike
