maybe a stupid question, but if its going to quit on you when you go full
rich on landing, then dont it also risk the chance of quitting if you go
full rich on a go around?
unless its just the high power that keeps it running and idle is what
kills it.

Yes. The mixture was too rich.
This is a common problem with big-bore engines when operated
above 3000 MSL.

What we teach at Colorado Pilots Association is to set the
mixture to 15 GPH as you enter the pattern at (near) cruise
power. That way the engine continues to run on the ground. :-)

Of course, if you do a balked landing, you MUST push the mixture
full in after you increase the power for the go around.

We took a newer 182 turbo to a 7000' elevation airport yesterday and
the engine quit at the end of the landing roll. I'm sure the mixture
was way too rich. It restarted without incident, glad we were on the
ground! We had the mixture set about 100 deg rich of peak TIT for
cruise at 9500. How should we have found the correct mixture setting
for power-off final approach, when the turbo is basically adding no
boost and we are at high density altitude? This is not addressed in
the POH. It does say full rich on takoff regardless of airport
elevation. Later that day, when taxiing for takoff, we set 1200 rpm
and leaned for peak rpm, mixture knob was out 1.5-2 inches to achieve
this.

When we returned home to 800' elevation, we checked the idle speed at
full rich, it was about 500 rpm, is this too low?

Thanks,
Barry
