As much as I hate tossing tools, sometimes it just makes better financial sense to buy a new one. By the time you factor in the parts and someones hourly rate, you will come out better off that way, I think.

Plus, you got 25 years out of the old one, so it owes you nothing, IMO.

I just noticed you mention the MSD. Is it possible that is throwing off your light? I don't know, just asking. Maybe try it on a regular car and see what you get.
