Maintenance
Cleaning the Air-Intake
Screen
Remove any buildup of grass, dirt, or other debris
from the cylinder and cylinder head cooling fins,
the air-intake screen on the flywheel end, and the
carburetor-governor levers and linkage. This helps
ensure adequate cooling and correct engine speed to
reduce the possibility of overheating or mechanical
damage to the engine.
