Agreed, when I said no more movement I meant in the centrifugal advance mechanism itself. There was no noticeable change in the gear clearance, and I didn't add to the shims.

Back in the 70's, GM sold a pack of distributor shims. They were .010 or .015 maybe ?
Ten to a pack , and it would take about half of them to shim up a distributor gear to remove most of the play there.
Always wondered why they left them that loose . GM must have seen as a hi-po issue, or they wouldn't have sold them.
I wonder if they are still available or somebody has them as NOS ?
