For a new motor you want it a little rich.Try your high speed setting at 3 1/2 to 4 1/2 out from closed.The screw below it is your idle screw,turn on all electronics you want a 1mm opening on carb turning the screw in will open the carb.Backing it out will close it adjust it with throttle pulled so you don't damage the slide with the screw.Your low speed setting is on the linkage,try one turn out from being flush with collar.This should get it up and running good luck,be patient and keep us posted on the outcome.
