You mention never finding a bad condensor - well I rarely find a good one in older engines. They are usually dead and sometimes shorted.
As the other guy mentioned, the spring-loaded impulse needs to be working to get good spark at slow cranking speed - like when pulling with a rope.
Magnets get weak but rarely go dead enough to be totally non-functional when in the magneto. Magnets go dead pretty quick if left out without any metal against them. That's why, when in a box, they usually have a metal "keeper" stuck to them. They are easily charged , anyway.
I suggest you take an ohmmeter and do some quick checking. Check the continuity through the points, check the condensor against ground (for a short) and also check for capacitance, and then check coil. Check the primary winding (low resistance) and secondary (high resistance).
I'll assume you're working on a heavy duty long-stroke engine and not a garden tractor short-stroke engine. Long-stroke engines e.g. AK, AH, BK, BH, HB, HK, etc. have external self-contained magnetos (or optional battery distributors) whereas the garden tractor short stroke engines do not (e.g. S-7, S-8, TR-10, S-10, TRA-12, etc.). Long-stroke engines with mags. , Wico or Edison have a point setting of .015". Fairbanks-Morse and Eisemann are set at .020". The very old engines used Eisemann and Edison mags.

Listening to Your Tractor - by Curtis Von Fange. Years ago there was a TV show about a talking car. Unless you are from another planet, physically or otherwise, I don’t think our internal combustion buddies will talk and tell us their problems. But, on the other hand, there is a secret language that our mechanical companions readily do speak. It is an interesting form of communication that involves all the senses of the listener. In this series we are going to investigate and learn the basic rudimentary skills of understanding this lingo.
