We try to stay on top of everything on this engine and not begrudge it a
penny. The mags are done every 500 hours and are only a couple hundred out.
We have the basics checked every 100 - 150 hours, pull the lifters, etc.
This has certainly paid off in an engine that has always run like a top with
not even minor plug fouling till now. It starts almost as well in the dead
of winter with a oil pan preheat as it does in the summer. Meanwhile, the
flight school planes are going "grind, grind, grind, grind, grind, grind,
grind, grind, grind..."

How long since the mags were overhauled? It is supposed to be done every
500 hours or so.
