This was a few days ago, but I didn't see a reply to John. My guess is
that you either have some point bounce or a worn distributor shaft. I
would check the points, and if that doesn't work, pull the distributor
and check it for radial play (maybe swap in another to see if that
helps). My car once experienced this but it seems to have gone away
when the switch was made to a Pertonix (II in my case, but that
shouldn't matter). The electronic points replacement "cover" up worn
parts that a point system wouldn't tolerate as well. Not the best way
to fix things, but if you are contemplating switching to a breakerless
sytem anyhow, this might push you over the edge...
please let us know what you find!
Good luck!
