Throttle Stop Screw

NOTE: Stop screw is set by manufacturer and should not be moved.

If basic factory setting has been changed, turn throttle stop screw counterclockwise until there is a gap between stop and screw. Turn screw until it just touches stop. Turn screw 1/2 turn (180 degrees) further. Check and adjust idle speed and CO.
