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, 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.
Note:
Not all Generator models have a Solenoid. Skip those steps if a Solenoid is not present.
1. Turn off the engine.
2. Close the fuel valve.
3. Move the air cleaner housing aside to allow access to the carburetor:
a. Loosen the knob and remove air cleaner cover.
b. Remove the foam filter and deflecting plate.
c. Remove nuts to allow air cleaner housing to be moved aside.
4. Place a bowl under the fuel cup to catch any spilled fuel.
5. Unthread the screws holding the solenoid in place.
CAUTION!
Carburetor bowl may have gas in it which
will leak upon removing the solenoid/bolt.
6. Disconnect the solenoid and solenoid seal from the bolt.
7. Unthread the bolt holding the fuel cup.
8. Remove the bolt, Bolt Seal, fuel cup, Fuel Cup Seal and Main Jet from the body of the carburetor assembly.
A carburetor screwdriver (not included) is needed to remove and install the Main Jet.
Note:
The mixing tube is held in place by the Main Jet and
might fall out when it is removed. If it falls out, replace it
in the same orientation before replacing the Main Jet.
9. Replace the Main Jet with the replacement Main Jet
needed for your altitude range (part 1a or 2a).
Note:
The Fuel Cup Seal and Bolt Seal may be damaged during
removal and should be replaced with the new ones from the kit.
10. Replace the Fuel Cup Seal (4a), fuel cup,
Bolt Seal (3a), and bolt. Tighten in place.

and tighten in place with screws.
12. Reassemble the air cleaner and reattach all hoses to it.
13. Wipe up any spilled fuel and allow excess to evaporate
