The air screw is not an air screw....it is a fuel screw. Turning it out provides more fuel flow - turning it in provides less fuel flow. (Carbs with air screws have the adjusting screw on the air cleaner side of the slide and do control air flow....the Savage carb is on the cylinder side of the slide and controls fuel flow).
You need to turn the idle speed down to around 800 rpm before you can adjust the mixture screw - as the recommended 1,100 rpm idle speed the slide has started to lift and is adding fuel - and this will make adjustment impossible.
If you can turn the screw all the way in and the engine runs smoothly - the pilot jet is too big. If you can turn the screw out more than 3 turns and the engine still runs smoothly - the pilot jet is too small.
The ideal pilot jet size provides the smoothest running when the screw is out between 2-3 turns for the best idle.
When making the adjustment the engine needs to be fully warmed up, the bike should be held upright and not on the centerstand, and you should do it as quickly as possible as the engine is getting no cooling air and the oil pressure is too low at 800 rpm.
