Hey guys, I was wondering if you go mixture full forward after start and then back to a taxi setting. Or do you go straight to lean taxi setting once it fires?

 

I'm in the habit of advancing to full rich after it fires and then backing it off. Never considered the other way but willing to learn. I guess I was just following the manual's starting procedure prior to leaning for warm up/taxi.

Our idle mixture link set fairly lean on the RSA-5 fuel injector, and it will not run anything less than full rich for the first minute or so. After that, lean 1/2 to 3/4.

I lean very aggressively when I lean on the ground. I want the engine to choke when I open the throttle just in case for some reason I forget.

It takes a bit of full mixture immediately after a cold start. Once it settles in about 30 seconds, I pull all the way back to a engine stumble and then slightly enrich to smoothness.

Trying to taxi, produces another stumble and needs a little more mxture

Forgot to add the caveat- my home field is at 4100'... At sea level, the mixture would probably need to be a bit richer, earlier.

My 231 starts at full rich.  In warm weather I lean immediately.  In colder weather I might let the engine accelerate a little first, to make sure it is literally running on all cylinders, before leaning.
