The dangerous time is really just before you start the

in both the J-3 and the 11AC and 7AC you can easily pull the door side
chock as you hop in without having to let go of the strut.

Right. Happily the engine is always hot, and the weather is never
frosty--I don't do XCs in the winter. The Cub I generally fly has an
alu prop and impulse starters (if that's the word), so will invariably
start on the first or (rarely) second flip.

I stand behind the prop with my left hand on the door frame and my
foot under the tire. (I would much rather the news story read: "He was
run over while trying to stop the airplane" than "He stood by
helplessly as the plane took off.")

I use two chocks with a light cord attached to them, which I loop over
the wing strut. They are offset to the inside. I've always been able
to give a little tug, then reel them in, while sitting in the rear
seat.

(At least, this is how I would do it if the occasion arose. Naturally,
I have never done this in real life, Mr. FAA Man.)

I remember several times cruising around in the J-3 and noticing that
I didn't have my seat belt on. Jumping in the plane, getting the
handhelds set up and all while the plane is running just caused me to
forget the seat belts.
The other day I was flying the sea plane and had the same thing
happen. Its easy to forget because you don't put the seat belt on
right away because you have to be ready to jump back out if you get
pushed back to the dock. Jumping out and beaching is always fun! Its
strange to be getting out of the plane while its still moving and then
trying to jump onto the dock at just the right time.

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.
