John-
The low speed needles (top ones) are set approximately 1.5 turns out from gently seated. The high speed needles (bottom ones) are set .75 turns out from gently seated.
These initial settings are just to get the engine started and running, don’t try to "fine tune" the adjustments much until you have the boat in the water.
