OPeRATION AT HIGH AlTITUDe
The density of air at high altitude is lower than at sea level. Engine power is reduced as the
air mass and air-fuel ratio decrease. Engine power will be reduced approximately 3 ½%
for every 1000' (304 m) of elevation above sea level. This is a natural trend and cannot be
changed by adjusting the engine. At high altitudes increased exhaust emissions can also
result due to the increased enrichment of the air fuel ratio. Other high altitude issues can
include hard starting, increased fuel consumption and spark plug fouling. To alleviate high
altitude issues other than the natural power loss, we can provide a high altitude carburetor
main jet at an additional cost.
The part number and recommended minimum altitude for the application of the high
altitude carburetor main jet is listed in the following table. In order to select the correct high
altitude main jet, it is necessary to identify the carburetor model. For this purpose, a code
is stamped on the side of the carburetor. Select the correct high altitude jet part number
corresponding to the carburetor code found on your particular carburetor.
