USAGE IN HIGH ALTITUDE REGIONS:
In regions with high altitude, the standard carburetor produces overly dense
combinations of fuel and air, which result in decreased engine performance and
increased fuel consumption. To maintain high engine performance at high altitudes,
install a high altitude carburetor main spray nozzle and re-‐adjust the adjusting
screw for idle speed. For usage in regions with an altitude of over 4,527ft (1380m),
contact your dealer to replace the standard carburetor and make needed
adjustments in advance. Even with a proper high altitude carburetor spray nozzle
installed in the engine, the power output of the engine will drop about 3.5% with
every 1000ft (305m) increase in altitude. If the standard carburetor jets are not
replaced and adjusted for usage in high altitude, the increased altitude effect will be
even more severe.
NOTE: Usage of the water pump in regions with lower altitude than the high
altitude carburetor spray nozzle is applicable, may result in decrease of
engine performance. The engine may become overheated and over-‐lean
combination of fuel and air produced, may cause severe damage to the engine.
