Mustn't have made myself clear: I'm suggesting disconnecting vacuum to diaphragm itself. Certainly can't run the thing on full engine vacuum -- tried that already (are you reading Martin G?). With centrifugal advance only you'll probably have lower advance curve, but at least could eliminate bizarre rotor movements as source of problem. I'm not comfortable with DeLo advance tied directly to manifold vacuum. Ford did the same thing in late 70's, routing through all sorts of valves and switches. Must be some performance or emission advantage new from factory, but does not age well. Probably only way I'm able to drive these cars home at all is because diaphragms no longer work. As part of de-emissioning I move spark advance to previous EGR activation port (advances with throttle plates). Replace diaphragm too.
