Correct initial position for distributor
RRR said: "It is beyond extremely rare for the distributor cam to wear, since the rubbing block is much softer. You do need to put some type of a good high temp grease on the cam, though. Don't glob it on, just a thin film."
That reminded me of the LubriCam saying. "Less Lubricam Last Longer!" Back in the late '60's and early '70's, that is what I used until I swapped to a electronic ignition and never went back to any points distributor.
