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.
