Another shining example of how useful this forum is, at least to me. I never knew, or didn't remember that with the dots lined up the cycle was in overlap. In my several engine rebuilds over a lot of years I always just set the gears properly and then never thought about them again, just put the #1 piston on the compression stroke and then used the timing mark to establish tdc. Good thing I never had an erroneous timing mark or I would have been a might confussed! Thanks All.
