I have a 91 ext 530. I was wondering what are the specs for the air screw. In a search I find any where from 3/4 to 1 1/2 turns out. What is the arctic cat spec for it.

I also have a 91 ext special with the 550. I am wondering the same thing for it. Air screw spec. The 550 has a small bog if you go wot from take off. If I feather it some get the rpms around 2500 then it fine. Just stumbles some coming off the idle. I have sprayed carb clean on the seals to check for leaks and I have not found any. I also put new jets in it. so they should be good and clean.
