From what I have read its an ignition problem. check the Dwell. It shoudl stay pretty steady at all rpms. varying abotu 1 degree might be ok wiht points, but it really shouldn't vary.

I have a Pertronix and it still does it, but for me it happens at idle only. Any ideas?

idle should be timing or fuel mixture.
