Vacuum Advance Chatter?
At idle, my HEI distributor is "chattering." Seems as it may be a vacuum supply problem to the advance? Problem came along with the Thumpr cam installation. No other problems. Motor runs fine. Anyone ever experienced this? Is there a simple solution?Leo

It started with the cam installation? Are you running a billet cam? They require a bronze dist. drive gear. Steel gear on billet cam will wear quickly, and may "chatter" as it goes away.

I have the melonized distributor gear, approved by Comp Cams for their steel cams.Leo Life is not measured by the breaths you take, but by the RODS that take your breath away.
