According to my contact at Firman Power Equipment, it's recommended that the generator be re-jetted if it will be consistently used at elevations greater than 8000 feet. Elevation and temperature have a large influence on the actual output of a generator.

In the owner's manual, Firman lists the part numbers for the re-jet kit that can be ordered directly from them. The kits include instructions. My contact tells me that switching out the jets isnt' too difficult, and that a person with average mechanical skills should be able to do it.
