Back out both screws another 1/2 turn. That's the factory setting as a base line.
One of the screws is low speed, one is high, and they are inter-dependant to a certain extent.
What you are after is a solid idle, with no hesitation when the throttle is snapped open, and a smooth acceleration to a steady CLEAN full speed (no/minimal smoke). Adjust the screws in 45 degree increments to acheive this.
