Idle Speed
- Idle is adjusted on a warm engine after the engagement of the clutch fan. Check that accelerated idle stop is not in contact with throttle lever and that accelerator cable is released.
- Adjust the set screw to obtain proper RPM. See Fig 1 . Turn fast idle cable sleeve nut to obtain a clearance of .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.
