MAINTENANCE Checking the Engine's Cooling Air Intake Check that the engine's cooling air intake is free from leaves, grass, and dirt. If the cooling air intake is clogged, engine cooling deteriorates, which can lead to engine damage. Checking and Adjusting the Throttle Cable Check that the engine responds to throttle increases and that a good engine speed is attained at full throttle. If doubts arise, contact the service workshop. If adjustments are necessary, they can be made as follows for the lower cable: 1. Loosen the clamping screw for the cable's outer casing and move the throttle to the full throttle position (no choke). 2. Check that the throttle cable is mounted in the correct hole in the lever, see illustration. 3. Push the throttle cable's outer casing until choke start position, see illustration, and tighten the clamping screw. 4. Set the throttle control to the choke position and check that full choke is obtained.
