If you're still using points\distributor system you are going to have continual problems over time. You don't indicate model, engine, or year so you can't really expect anybody to diagnose your possible problems. You would be well served to purchase one of several , quality manufactured , solid state ignition systems that are currently available . i.e. , MSD, Jacobs, Davis Unified Ignition , etc. and several more that I can't think of at the moment......fordy
