Can anyone tell me how many turns out on the air screw on a 2 stroke 90cc polaris quad. Mine was at 4 turns and the quad would not run unless I had choke on. I turned it in 1 turn and it seems to run better but I still think it might be off a little. I cant figure out how it got to 4 turns unless my kid was messing with it. Thanks.

 

try another half to 3/4 of a turn and it should be good

 

You saying another 3/4 of a turn in, so it would be at about 2 1/4 turns out from being totally closed.
