It’s important to keep the cam in your distributor lightly lubricated to prevent premature wear of the heal of your points. A light smear of grease is best, unless there is an oiling felt provided – which should be lightly oiled periodically. Put a dab of oil on the points post, too – plus a few drops on the screw underneath the rotor arm, which will work its way down to the bob-weights of the mechanical advance mechanism.
