That was interesting.

Found out later you should never hand-prop an engine like that one
(something to do with the mags kicking over too soon or something like
that.)

Why would the mags kick over too soon? Aren't they preset and fixed
so that they don't kick over too soon?

Or did you mean that the preset (around 26 degrees BTDC) is too
advanced for hand propping?

One the 11AC I flew, we had one mag timed for propping with the
impluse and the other timed normally. We would start on the one mag to
prevent kickback (although you could start on both). Once the engine
started you just turned it to "both". I suspect that that is actually
the same even on my Mooney. I think the starter kicks out one of the
mags so you actually only start on one until you release the starter.
