I have rebuilt and upgraded original equipment stovebolt point-type distributors by boring out the top of the housing and installing a Torrington needle bearing, and adding a hardened steel sleeve to the distributor shaft. I remove the grease cup, spring, and plastic disc on the side of the housing, and replace it with a 1/8" pipe thread grease fitting. That procedure totally eliminates the shaft wobble and dwell variation that has been a problem since those distributors were new. It's also possible, but not really necessary, to add a bronze bushing at the bottom of the housing.

Can you see this wobble-related dwell variation on the meter? And if so, how much needle bounce is considered normal vs problematic?
