A bungled jump start (12/6, reversed polarity . . .) shouldn't be a factor with your problem. The mag is an isolated unit, totally independent of the rest of the tractor's electrical system.
It could be a weak magnet, but it's more likely your problem is going to be coil or condenser. Either one will require removing the mag, so all the precautions of having the motor set up at TDC on compression on #1 before removal (and then not disturbing it) will make the job less prone to problems when poutting things back together. Both the coil and the condenser will require removing the rectangular cover on top and the cover on the motor side of the mag. Handle the two insulators for the stud on the condeser carefully (the little brown ones, one inside, the other visible on the outside around the connection for the ground wire), they're not easy to come by.
Before getting into that , please do try shining up the points, they'll look good but a little corrosion on them will keep yo from running.
One other pesky little thing that pops up now and then, too, is a short from the wire between the consenser and the points where it passes though the distributor body. That's be worth a look.
Worse comes to worse, you can have it rebuilt or swap it as a core for one already rebuilt. If it comes to that, I've heard good things about the shop at the link below. Theres' also Magman, but his link isn't working. Maybe someone else will have a way to contact him.
Good luck and come back for more if we can help. Theres' better hands with mags than me around here.

"Barry Seiler, owner of Country Town Farm Supply store used to invite people up to the Johne Deere store. He would give hats and a free meal for everyone that brings a tractor."
