I'm at my wits end with points. I have a 63 ford 4000 and when it runs it runs great. The problem is trying to get it to run. If I let the tractor sit for more than a day or so it won't fire at all. I have to pull the distributor cap off and swipe the points a few times with some 1000 grit sandpaper. Once I do that it runs great again. I have tried points from tractor supply, napa, and even from this site. The tractor is setup for 12 volts. The coil is a generic 12v coil from napa with "no external resistor required" stamped on it. The points are set correctly and the ignition shuts the voltage to them off when the key is out. It is like they get a thin film of corrosion each time they sit. The points don't have any burn marks or discoloration on them. If I shut the tractor off and re-start it immediately or a half hour later it runs fine. It is just when it sits overnight. Any ideas? I'm ready to put in a pertronix kit if it comes to that.
