Carburetor Adjustments
Low Speed Needle: 1.5 turns out as a starting point, adjust for a
smooth idle and a reliable transition to high throttle
High Speed Needle: 1.5-2 turns out from closed, adjust needle to peak
RPM, if engine slows or dies at full throttle, the high-speed
mixture is likely too lean
