I just installed a Pertronix on my '74 fitted with Webers. Set the timing to 35 degree advance at 6000rpm (but it actually stabilizes around 4500).

Had some problems with the engine dying on acceleration prior to the Pertronix install, which went away after. Figure I had bad points.

Now with the Pertronix the engine doesn't die but it is very slow to return to a normal idle. It will drop to about 1500rpm and very slowly drop from there.

I balanced the carbs and set the mixture. Replaced one of the throttle links to make sure everything there is ok. Left the idle setting a little high (~900rpm) while fiddling with it.

Checked the vacuum line to the distributor and at the carbs and all seems ok.

A mechanic friend of mine suggested that my distributor bearings may be worn, causing the gap between the magnet and pickup on the Pertronix to vary. He thinks this could cause the idle problem.

Does this make sense? Any other thoughts? How would I check for this (or maybe I should just go back to points?)

Thanks in advance!
