After each small turn, I mean a hair, you need to blip the throttle and wait about 30 seconds or more for the engine to settle again. That is how you do it. Quick and dirty way is to measure the voltage at the battery with the engine running. Cut that voltage in half and there is your %50 duty cycle value. Basically try and get close to that. You may need a new Lambda tower if your value is swinging that far. They are only a few bucks and fairly simple to install. The lower the voltage the richer the engine and higher voltage is lean. Clockwise to en-richen and counter clockwise to lean!
