SOLVED!....sort of. Where's there's spark.. there's no fire!

I cannot see the upper timing marker. I haven't had to adjust the timing in several years. It has not drifted any. I had a shop do it the last time as it requires two people using the lower one. One to watch marker and the other to move distributor. Mine requires disconnect a sensor wire by the distributor, but it is later model with a remote coil.
