HIGH ALTITUDE ENGINE OPERATION:
Have an authorized service center modify this engine if it is to be run above 2000 feet [609.6 m]. Failure to do
so may result in poor engine performance, spark plug fouling, hard starting, and increased emissions. Carbure-
tor modification by an authorized service center will improve performance and allow that engine to meet the EPA
(Environmental Protection Agency) and CARB (California Air Resources Board) emission standards.
An engine modified for high altitudes can not be run below 2000 feet [609.6 m]. The engine will overheat and
result in serious engine damage. Please have an authorized service center restore high altitude modified engines to
the original factory specification before operating below 2000 feet [609.6 m].
