I have to agree with some of the other people on here. Are you sure it's the ignition? I also run the Mopar ignition on my car. In the past 22 years I have only had to replace the box itself only twice. My car stays in a shed usually from November until March. During that time, I will usually start it and let it run for a while every 4 to 6 weeks. My carb. is a 750 DP Holley without a choke. I have to pump it a few times, but it always fires up, and after about 5 minutes it will idle by itself.
