HIGH ALTITUDE ENGINE OPERATION
Please have an authorized service center adjust this engine
if it is to be run above 2000 feet. Failure to do so may result
in poor engine performance, spark plug fouling, hard start-
ing, and increased emissions. Carburetor adjustment by
an authorized service center will improve performance and
allow that this engine meets EPA (Environmental Protection
Agency) and California ARB (Air Resources Board) emis-
sion standards. An engine adjusted for high altitudes can
not be run at 2000 feet or lower. In doing so, the engine will
overheat and cause serious engine damage. Please have
an authorized service center restore high altitude modified
engines to the original factory specification before operating
below 2000 feet.
