73 dart sport project

I don't know much about wiring MSD ignitions into mopars, but I have heard about this problem a lot. Seems everybody says it has no spark when cranking, but tries to start as soon as you let off the key, or something of that nature.

I had the same thing happen to me along time ago with a 6AL. I went back to the factory ignition. Years later when I discovered the internet I read about the same problem.

Did you post a thread in the ignition section? I am sure its an easy fix.
