For my 2004 MXZ 600 HO the shop manual say 1.5 turns out.
I set mine to 2 full turns out though and it still seems like it may be a bit lean based on the color of the plugs. You should look in the tech specs in the shop manual for your sled: they will list that in the technical specifications section. I found my shop manual online and I an guessing you can as well.
You need to test and tune. Turn the screws and drive it. Look at the plugs and adjust accordingly.
