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 and
increased emissions. 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.
