The only other answer is some airplane elf came and reindexed your prop
in the middle of the night :-)


May not be as strange as it sounds.

Maybe someone needed a prop. They stole one, put it on your plane and
stole
yours. That way the one reported as stolen is on your plane, which you may
never find out about. Mr prop theif winds up with yours, which never gets
reported.

Nope; nice try, though. I'd already made 3 stops that day in which
everything appeared normal.

I would not be too concerned about it. Remember -- the rings rotate in
their lands and can sometimes end up with all the gaps lined up, thus
changing the effective compression. This appears to be the case here,
since the prop is now stopping in the usual place.

To add fat to the fi is it always the same blade on the same side, or
do they swap?

I once prop-positioned a cutie on the ramp... If you must know, I
crashed and burned... :-(

How did that happen, did you pull the 'we're out of gas' trick?

She informed him of the "Pop-up" TFR:
Sorry, can't.
Huh?
The "President" is coming for a visit.
Huh?
The "P-R-E-S-I-D-E-N-T" is visiting ...for a week.
Oh .....pause ....OH! ....pause .....Doh!

But it's not; that's the problem.

It stopped in the usual place 3 times at 3 different shutdowns Sunday, then
stopped in the new place when I got home Sunday night.

They swap.

Update:

I went to the airport first thing this morning to turn the prop with the
engine cold. As before, I felt good compression at each cylinder, and the
prop stopped at 02:30/04:30.

So I ran the engine for 3-4 minutes, just to get the oil a little warm, and
shut it down. Voila': the prop stopped at its usual 09:00/03:00 position.

I don't know WTF to think, now.

Wait a minute, yes I do: I think I'll have a couple of Coronas and forget
about it..

Dan -

Does the engine always feel tight only when hot? If so, as a
precaution, do an oil analysis next change or next time the cowl is
off. Don't waste money on a more formal compression test.

You don't have top end trouble, but you just might have a problem at
the bottom end.

Like what?

I mentioned that to my wife a few days back... and got slapped...

Like what? Possibly, and I want to emphasize just possibly - a shelled
out camshaft system contaminating the crank bearings such that they
shrink onto the crankshaft on cooldown. An oil filter check (assuming
there is one) would also show if something is shelling out. Maybe even
just looking critically at the oil on the dipstick would show aluminum
or steel "paint" immediately after a shutdown.
