5) High AltitudeOperation
Athighaltitudes,thestandardcarburetorair-fuelmixturewillbe excessivelyrich.
Power outputwill decrease,andfuelconsumptionwillincrease.High altitude
performancecan beimproved byinstalling asmaller diametermainfueljet in the
carburetorandreadjustingthepilotscrew. Ifyoualways operatethegeneratorat
altitudeshigherthan 3,300feet(1,000meters)abovesealevel,haveagenerator
dealerauthorizedbyour companyperformthiscarburetor modification;orthe
generatorshouldbeusedwithlowered powerrating.
Even withsuitablecarburetorjetting, enginepower will decreaseapproximately3.5%
foreach1,000 feet(300meter)increasein altitude.The effect ofaltitude onpower will
be greaterthanthisifnocarburetor modificationismade.
Ifanenginejetted for high altitudeisusedataloweraltitude, the
