Wouldn't one tooth on the cam gear be 6.66 degrees on the cam? Or do you figure it from the crank side? It's pretty easy the set up and get close enough when building an engine but changes later can be a pain. Keeping an adjustable gear in place would be tough and the results of a failure could be expensive. It is fun the think about though. With our press on cam gears maybe something in the hub or some kind of wedge?
