At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease
and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard
starting. Operation at an altitude that differs from that at which this engine was certified, for extended
periods of time, may increase emissions.
The fuel system on this Engine or Equipment may be influenced by operation at higher altitudes.
Proper operation can be ensured by installing an altitude kit when required. See the table below to
determine when an altitude kit is required. Operating this generator without the proper altitude kit
installed may increase the engine’s emissions and decrease fuel economy and performance. Kits may
be obtained from any dealer, and should be installed by a qualified individual.
This high altitude jet is to be used at elevations above 3000 feet.
At elevations above 8000 feet, the engine/equipment may experience decreased performance,
even with the high altitude kit.
If a carburetor is replaced, the proper high altitude kit jet will need to be installed into the
replacement carburetor.
