Today I removed the Pertronix and put points back in. The car ran much better but I have very high idle even when the idle stop screws are backed out all the way. (Webers). Not sure if I have a different distributer in there but the plastic piece that covers the distributer shaft lobes sat very "low" and the Pertronix has a plate to lift the -whatever you call it- piece, but mine looks like it needs to be lower-not higher. I'll keep trying until I get it right- I can't see having someone else tune my car after everything I've done that miraculously does work. If anyone has a picture of how their Pertronix fits under the cap I would be grateful!
