Twice now this happened:
C182B O-470L Engine 460 hrs since overhaul in 2011, bendix/tcm mags overhauled at the same time.
The engine gets real rough for 4 or 5 seconds then goes away.
First time was climbing at 10,500 with carb heat on, mixture leaned ~ 150 F rich of peak.
Second time cruising at 7,500 with, no carb heat this time, mixture leaned same as before. I had been cruising at 2300 RPM and was advancing the prop to 2400 rpm when it happened.
Both times I was about an hour into the flight.
Of course when it happens I usually change the position of the carb heat and mixture but by the time I do those things it's over.
I suspect an intermittent magneto problem, because the engine feels about like it would with one magneto off when it happens.
Is it possible that a magneto could be failing intermittently or am I on the wrong track.
