- 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 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.IDLE SPEED SPECIFICATIONS
