This flow of air carriescombustion heat away from the engine.Overheating and engine seizure can occur when:• Air intakes are blocked, preventing cooling air from reaching thecylinder.• Dust and grass build up on the outside of the cylinder. This build upinsulates the engine and prevents the heat from leaving.Removal of cooling passage blockages or cleaning of cooling fins isconsidered “Normal Maintenance”. Any failure attributed to lack ofmaintenance is not warranted.0.65 mm(0.026 in.)
