Air Cooling System
Over time debris may accumulate in cylinder cooling fins and cannot be observed without partial
engine disassembly. For this reason, we recommend you have a qualified Yard Force service
dealer clean the cooling system per recommended intervals (see Maintenance Schedule). It is just
as important to keep top of engine free from debris. See “Clean Debris”.
Carburetor Adjustment
The carburetor is equipped with a non-adjustable idle mixture valve. Top speed has been set at
the factory. If adjustment is required, see an authorized service dealer.
CAUTION!
Excessively high operating speeds could result in minor injury.
Excessively low speeds impose a heavy load.
