I've never really had to mess with them much, yeah, I know, I'm a younun. But geez, is it even possible to get them working perfectly, ever? And then right about the time you do get them to work somewhat, you leave the ignition on and fry them! Ugh. I've been fumbling with the ignition in my flat rod .Mostly because on the way home from the Off-Road Expo I stunk like unburned fuel from the exhaust of the poorly running engine (I fried the points, again). I think I got it set right now but those suckers are coming out pronto. 1970's and electronic ignition here I come. I just bought a Pertronix.
