This flow of aircarries combustion heat away from the engine.Overheating and engine seizure can occur when:• Air intakes in the crankcase are blocked, preventing cooling air fromreaching the cylinder.• Dust and grass build up on the outside of the cylinder. This build upinsulates the engine and prevents the heat from leaving.Removal of crankcase cooling passage blockages or cleaning of coolingfins is considered “Normal Maintenance”. Any failure attributed to lackof maintenance is not warranted.
