I rebuilt a distributor today and installed a Pertronix unit, and ran into a problem that I never had/noticed before. This was a 039xxx205A distributor and the problem was that the little 'finger' in the bottom right was running into the Pertronix mounting plate. This interference was completely eliminating any vacuum advance.
5 minutes with a file and it was all fixed. If you've got a Pertronix, this would be something to look for and should be visible simply by removing the cap and rotor and jumping in the engine bay with a flashlight. Always learn something new.

Well, since this was just a distributor rebuild, I discovered it when I was testing the vacuum canister. I would suck on the advance tube and it would only move the slightest bit. I knew the canister was working (tested it before installing it) so I started pulling parts off until I found the hangup.
But if a running car were suffering from this 'condition' it would lack some acceleration oomph, especially WOT acceleration. |
