Leaning mixture after start-up

Shock heating your engine to clean the plugs off isn't so good for it either. Leaning during taxi prevents the need for that.  We have only had to do it once in 100 hours, I was checking someone out and he let it idle at 800 rpm a couple minutes.

I have leaned carb engines on the ground and I always tried to keep the engine from 1000-1200 rpm.  It always felt Like it had an effect there, yes, but not at 800 rpm idle.
