I can verify the B stock distributor is not "optimal."

My use is a Model B engine converted to the Gordon-Smith air compressor. A centrifugal is required because the engine/compressor has two operating states: "Idling" and waiting to pump air, and "Running" at nearly full throttle. A distributor has to cover both states in this case.

Rebuilding the B distributor, I found by using a variable speed drill to power the distributor that it "hangs up," apparently on the ramp of the "cam" within. Grease in this area helped - until the grease was thrown off at high speed.

A replacement "core" from Renners was better, but I have seen it hang up.

I still haven't found a resolution I'm satisfied with - so I'll be watching this thread as it develops.
