This is indicative of having had a spike on one point and a corresponding
hole in the other. If you were still having the mismatch it could indicate
worn distributor bearings.

Are your plug leads one position out? Or it could be that the body has worn
to accept the clamp in one area and the clamp needs slackening a bit more.
