Also This AM I bumped it another 4 degrees; slight pinging on hard accelleration, and no backfire. Total static (no vacc hose, idle) advance is now about 12btdc. This seems high to me, in spite of the TSM. I may yank the distrib sometime to see if the mech advance is sticking or something; I'll RTFM and find out what total mech adv is supposed to be (after I ascertain just what the hell distributor is in there! Some late-ish model Duraspark job). I suppose I should get one of those recurve kits (if I didn't already) and do that then. I did take your hint though on failing duraspark boxes; I brushed off an extra one and put it in the trunk.
