Cleaning the Air Intake
Screen
Before each use remove any build-up of grass, dirt
or other debris from the cylinder and cylinder head
cooling fins, air intake screen on flywheel end, and
carburetor-governor levers and linkage. This will
help insure adequate cooling and correct engine
speed and will reduce the possibility of overheating
and mechanical damage to the engine.
