  2. Adjust the set screw to obtain proper RPM. See  Fig 1 .  Turn fast idle cable sleeve nut to obtain a clearance of 0.04" (1 mm) between fast idle cable end and fast idle stop. Start engine and warm to operating temperature. Compress the fast idle stop and check idle speed. Engine speed should be 1200-1400 RPM. Adjust if necessary. Adjust cable and clearance.
