It's been mentioned a few times to fatten the idle up but I've seen this go both ways. I've seen that you can get a high idle on a hot engine when it's fat as well as lean. Cold and rich the idle is low but then you go for a spin and the idle is high because it's burning everything off and needs to be leaned out a little.

I start with 1 1/2 turns and then adjust everything hot. I go for a ride, then make adjustments in and out of gear while still warm and that is usually where it needs to be. If you're not getting much mixture adjustment with the bleed screws, you have to change the idle air bleeds.
