Those coils are dang near bulletproof. If it has secondary winding continuity, it’s good. I agree, take the points apart, degrease everything, and polish each contact individually. Be careful not to lose any of the many little insulators. Reassemble & adjust point gap to .020" You probably will have spark.

The clearance between coil and rotating magnet is important. I’ll have to hunt for the specs that I stored somewhere. Most important, it should not be rubbing.
