Flying the other day I was leaning out the mixture and noticed exceptionally high EGTs. So I fed in more gas and she cooled down into the green. Leaned again and again, high EGTs. Tried it a 3rd time and it was normal. This puzzled me. I also felt a surge of power once while taking off. Wasn't real sure about that either. I landed and before departing did a routine mag check. The engine died on the left mag.
Uncowled and looked for obvious problems. None found. Started it up the next day to troubleshoot. This time the routine mag check worked fine but the engine died while checking the left p-mag's "internal" power. I removed the left P-mag and discovered the drive gear was "crunchy" when rotated. I just went through this with the right p-mag about 20 hours ago so I am sure the magnet has once again dislodged and partially disintegrated. We'll see if I have to pay for new circuit boards again! The P-mag is on its way to EMAGair....
