Bob, under the plate the points mount on are weights and springs that cause the advance as it speeds up. The shaft the rotor and points operate with is actually a separate shaft form the one that drives the distributor with one shaft being inside the other. That may be gunked/rusted and need to be cleaned and lubed. with the engine not running you should be able to use your hand to turn the rotor forward and backward a few degrees, with the springs returning it when you release it.
If you are not part of the solution,
you are part of the problem!!!

Thanks John. I've never had that plate off and was a little concerned that I may screw it up if I went digging in there.

I just went out and held the drive gear and turned the shaft. It was stiff. I lubed it again and worked it several more times. It appears to be freeing up a little. I will continue to lube it and move it for the rest of the day and reinstall it in the morning.

Thank you again.
