magnetos
a non flying friend (he did have some lessons many years ago) was questioning me about ignition systems on my aircraft, I have two stroke and 4 stroke Rotax engines in my 2 aircraft. His concern was about the reliability (or lack of) of magnetos fitted to aircraft engines and I said that the systems fitted to Rotax engines are basically fit and forget. Not so, he said, the systems fitted to Lycomings and Continentals in GA aircraft. Every 2 or 3 seasons.........
So what does go wrong with them? I have heard stories about impulser faults and, presumeably, the points are as prone to wear, adjustment and fatigue as they were when cars had points ignition systems.
Of course the Rotax circuits don't have any points or moving parts and seem to be much better for it.
