Loosen basic throttle setting adjustment screw lock nut. See Fig 1 . Turn screw until throttle is completely closed. Tighten adjustment screw until it touches throttle lever and then turn an additional 1/4 turn (turn additional 1/2 turn on 940 GLE). On all models, tighten lock nut, making sure not to change adjustment. Recheck basic throttle setting.
