Points?! Me, points!? Not on your life in this car! Duraspark II, big Ford coil, 8mm wires, big cap, ...! It's either the Duraspark distributor, or the timing light, that's got the jitter. I may repeat the test and fiddle with the placement of the clamp-on pickup to see if it's that. Otherwise, it's a bum distributor. I've not found a good-as-new used or rebuild distributor (or carb, or starter, for that matter) in years. Cardone is fair, and Tomco is crap. Part of the problem is simply cores are all worn out I guess. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
