Hogflyer, Are you talking about the low speed needle? From the manual the low speed is the black screw on top of carb with a lock nut, is this right?
The low speed needle is the screw inside the blue limiting collar. If you want to adjust it you have to loosen the small allen screw on the collar first.
Horizon told me one time that the factory settings were 1 1/2 turns out on both high and low needle settings.
