OK, I'm going with .020" @ highest point on cam. And Racer, I respect your knowledge but your bedside manner needs some work. Don't assume you are always talking to an idiot. By the way, my 1962 Evinrude electric start Lark's flywheel does NOT have any timing marks on it whatsoever. It's got teeth for the starter, It's got teeth for the generator. belt. It's got a notch for an emergency start cord. It's got a "2" stamped on it. That's it my friend. Timing marks? Zilch. What would these mythological timing marks look like pray tell? - Pete
