Among the problems with diagnosis of old car running problems is that a problem such as a rough idle can be caused by a multitude of causes. Chief among these is a vacuum leak and I would begin there.

I understand many have luck with Pertronix and similar substitutes for breaker points. These are in my opinion one size fits all solutions to problems that don't exist.

Properly installed and adjusted breaker points available at NAPA will last our average tenure with the car. Yes electronic ignition is far superior to that of breaker points. But that does not include some of the one-size-fits-all under the cap substitutes that offer poor heat rejection and often fail without notice on the Road.

If you insist on using pertronix make sure your mechanic realizes that in most cases the quail must have a ballast resistor in its primary circuit but the module itself must be fed directly from the battery or ignition switch and not through any ballast.

I have a mechanic who has not been able get a smooth idle for me, I replaced the distributor with a pertronix 2 times, put back original distributor runs better, put in new Edelbrock carburetor, fixed intake manifold vacuum leak, also ammeter needle jumps when rough idle occurs, was worse with pertronix. Thanks in advance for any ideas on this issue.
