Incidentally, the situation with the magneto is really no different than with a conventional automotive-type battery, point & coil system.
In the automotive system, event #1 is timed by adjusting the dwell angle, which is set to the best compromise between maximum spark energy / reliability and coil operating temperature.
Then event #2 – the ‘real’ ignition timing is usually adjusted by turning the distributor housing after loosening the base clamp screw. And just as with our magnetos, changing the point gap in the automotive system affects both events #1 and #2 – that is, it alters both spark timing and energy.
Same situation, really, just with a couple different considerations.
