There really isn't any correct adjustment proceedure. You can adjust 
it to try to get the smoothest transition from cold to hot idle, but 
keep in mind that the AAR has absolutely NO EFFECT once you're off 
idle.

Way too many people get sidetracked, thinking that the key to some 
other problem is to get the AAR "just right."

That's extremely common. The pot metal housing has warped, and your 
transition will never be smooth until this is fixed. I rebuild these 
to fix this problem for $25.
