Mixed Info: PWK 36 Carb Air Screw In or Out...

I was under the impression that turning it OUT (counter clockwise leans it out...as it adds more air)... or is it the opposite.... I have heard both repeated... Mine is at 1 1/4 now.

2 stroke

air screw

-in = richen

-out = lean


4 stroke

fuel screw

-in = lean

-out = rich

Cr 250 is correct. A lot of people try using the terms interchangeably and it's wrong. Also some call it an air/fuel... Well it only is adjusting one of those so air on a smoker and fuel on a thumper.
