In the mid 70's after only 10 miles of driving in town my hemicuda would load up. Very annoying, so you would have to drive around the "loop" outside of town and drive it wide open to clean it out. (Not that I minded.) I was a teenager, I didn't know anything. I would clean the points with a thing called a flexstone that I got from the Snap-On man (wish I knew where I could get one of those now) and that didn't help. I sure wasn't going to work on those AFB's for fear that it would never run again. Electronic ignition was the greatest mod ever for a Street Hemi. I don't think I've ever heard one miss since. Give the inventor of that the Nobel Prize. It changed everything.
