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.

Never heard of "Hot Spark" before - do you have a link? Can you leave your ignition on like a Pertronix2?

Personally IMHO if your engine is "close" to stock either run stock or this. http://www.hot-spark.com/Hot-Spark-SVDA034-3BOS4U1.htm
You need both vacuum and centrifugal advance for a Porsche Type IV or 1750 SC/912 engine. |
