Pick a starting point. Cyclic's method is as good as any. Open up the engine to WOT and tune up the HS needle. Slowly close the carb to reduce RPM. When the engine begins to stumble hold it there. Pinch off the carb line (pinch test) and determine if lean or rich. Make SMALL adjustment to LS needle. Return to WOT and retune HS if needed and then reduce throttle as before to "stumble point" again and repeat LS tune until you can get down to idle speed. Recheck all needles and go fly.
