High Altitude Operation Above 3000 feet
WARNING! TO pREVENT SERIOUS INJURY FROM FIRE:
Follow instructions in a well-ventilated area away from ignition sources.
If the engine is hot from use, shut the engine off and wait for it to cool before proceeding. Do not smoke.
NOTICE: Warranty void if necessary adjustments are not made for high altitude use.
At high altitudes, the engine's carburetor, governor (if so equipped), and any other parts that control the fuel-air
ratio will need to be adjusted by a qualified mechanic to allow efficient high-altitude use and to prevent damage
to the engine and any other devices used with this product. The fuel system on this engine may be influenced by
operation at higher altitudes. Proper operation can be ensured by installing an altitude kit at altitudes higher than
3000 ft. above sea level. At elevations above 8000 ft, the engine may experience decreased performance, even
with the proper main jet. Operating this engine without the proper altitude kit installed may increase the engine's
emissions and decrease fuel economy and performance. The kit should be installed by a qualified mechanic.
