360 timing issue, retards before advancing?

67Dart273, the distributor doesn't feel worn out. I had it completely apart, bushings look good, feels tight, turns smoothly. I lubed all the moving parts, and they all seem to move freely.
I do have 4 or 5 more distributors to work with. Anything I should be looking for?

Unless you luck out and have an unknown MP distributor, or one that someone recurved already, you are going to have to re-curve anything you find. Main thing, I guess, is good condition and bushings in good condition. Ticks me off. You used to be able to buy a Mopar bushing kit for these distributors. They were cheap.
