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.
