In order to assure peak performance of your engine,
inspection of the engine exhaust port may be necessary after
50 hours of operation. If you notice lost RPM, poor
performance or general lack of acceleration, this service may
be required. If you feel your engine is in need of this
inspection, refer service to any non-road engine repair
establishment, individual or authorized service dealer for
repair. DO NOT attempt to perform this process yourself as
engine damage may result from contaminants involved in
the cleaning process for the port.
