D. COOLING SYSTEM MAINTENANCE.
The cooling system relies on cooling air entering
the engine through the bottom engine grille located
between the fuel tank and starter. The cooling fan
pushes this air through the cylinder fin area and out
the rear grille openings in the engine cover.
IMPORTANT
To maintain proper engine operating
temperatures, cooling air must pass freely
through the cylinder fin area. This flow of air
carries combustion heat away from the engine.
Air intake
Overheatin\J and engine seizure can occur when:
1. Air intakes are blocked, preventing cooling air
from reaching the cylinder.
2. Dust and grass build up on the outside of the
cylinder. This buildup insulates the engine and
prevents the heat from leaving.
Removal of cooling passage blockages or cleaning
of cylinder fins is considered "Normal
MAINTENANCE
Maintenance". Any resultant failure attributed to
lack of maintenance is not warranted.
E. CLEANING THE CYLINDER FINS.
(Check Periodically)
1. Remove any dust and dirt from between the
fins.
2. If greater access is needed to thoroughly clean
the fins, remove the engine cover as illustrated.
