Turning out the air screw and rising the revs of the engine, of course you have to correct in parallel the vertical stop of the Piston to reduce speed down (the bigger screw besides the idle screw). If you find a Balance your engine will work with a very slow plop, plop, plop.
Turn up revs to your idle Speed which you like .
