I want to thank both of you for great replies. I currently have the head off and can see the piston movement. Since the arc of the wrist pin is oval, there are a few degrees when the piston is at top that there appears to be no movement in the piston vertically. I can move the ring gear several teeth in both directions and the piston does not seem to move. I made a nice pointer and it works with the new balancer, I just wanted to make sure I am starting at 0 degrees. By the way Tom, that snout tap tool is one of the best tools I have ever used considering the investment.
Thanks
Warren
