When you run the prelanding checklist on downwind and pull the carb
heat, that's a pretty good time to go to full rich (if you want to) in
anticipation of a go around. Otherwise, leave it where it is until
you pull it the rest of the way out to shut the engine down as you
park. If you make a go around, push the mixture to rich, carb heat to
cold and apply full throttle. Some folks don't like the extra work
with the mixture at that time, so they go to full rich on downwind,
base or final to be ready for a go around. They lean again after
turning off of the runway to avoid plug fouling.


Argh! This business about going to full rich in anticipation of a
go-around might be OK for flatland pilots, but it is not a good
practice generally. If you are at a high density altitude (could be a
med. altitude airport in the summer), going full rich for landing
might leave you in the trees if you attempt a go around. I've seen
this happen more times than I care to remember.

Rather that repeating the inaccurate landing checklist item,
"mixture - full rich", how about a new one. "Mixture - set
appropriately".
