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.

Tradisrad you are ok, we checked for it when your pertronix was installed. , I have for years since my first pertronix in a Bug, bench tested the dizzy advacne / retard operation every time i do a pertronix install. also areas of concern are the rotor hitting the unit, some roters are wider and can hit them. So make sure you test for rubbing with the ROTOR INSTALLED ALSO!!!!! in addition to the part mcmark pointed out. also note you can buy different pertronix ,some modles will fit better than others, but always please check the advance,/ retard operation on each new install, thats part of the install. |
