congrats to a safe landing!

back when i owned a cherokee 140, my plan
was to ....intermittently pull the mixture to full cutoff...

Which reminds me of a dawn takoff and climbing through a thin layer,
noting the engine going to auto-rough, and pulling the carb heat all the
way.
But the engine fell quiet, so I pushed it in again.
So the engine went to auto-rough again, and I pulled the carb heat
AGAIN, with the same effect.

Then I looked at the knob - the mixture control - ##!!- after hundreds
of hours in that very plane too!

Never did THAT again.
