Can you give me some more details of how to determine TDC with the head on and what is the valve position when TDC is achieved? Can I put a long thin rod in the number one spark plug hole and determine when the piston is at top dead center? Should the dot on the cam gear and the dot on the gear on the crank line up on top dead center? If the dots do not line up at top dead center on number one piston then I know the cam gear has slipped? I have never rebuilt a flathead engine or set the timing marks before.
