Sorry so late getting back to the group... away travelling on business.

Carb heat had been on since downwind. I was taught to put carb heat on as
part of my downwind checks every time, when doing manouvers at lower
throttle settings, and approximately every 15 minutes during cruise... which
I'm pretty faithful to. It is also standard part of my runup (both at 1700
RPM and at idle).

This was my third circuit. Carb heat was applied during downwind for all
three of them.

You make a good point that when I did my shutdown after restarting, I didn't
have carb heat on, so the engine not quiting and showing 800-900 could be
because carb heat wasn't on... though it didn't quit on my first two
landings either.

idle setting from being too low that probably needed adjustment. Even
so,
during shutdown (after restarting), idle setting on the throttle was
still
800 - 900 RPM, which should be enough to keep the engine running I would
think.

Did you have the carb heat on when the engine died in the air and off
when you couldn't make the engine fail on the ground? Maybe the idle
setting was low enough that the additional RPM loss due to the carb
heat made a difference.
