Operating on
Highlands
On highlands,
the standard cal'bul'etor airlfuel
mixture is relatively too rich so the engine
performance
may be
impaired while
the
fuel consumption may increase.
a-:
High altitude
performance
can be improved by installing
a
smaller diameter
main
fuel
jet
in the
carburetoq
and
readjusting
the idle
needle
screw
aird
the idle adjust screw.
If
you
always
operate
the engine at altitudes higher than
1830m above sea level,
ask
your
dealer for adjusting the
carburetor.
The engine
power
will
decrease
approximately 3.5oÂ
for
every 305,meters increase in altitude, even the
proper
main
jet
of
carburetor
is
used. The affect of altitude on
power
will be
greater
than
this if no
carburetor
modification is
conducted.
CAUTION
The
engine equipped with the main
jet
applicable to
highlands may be damaged seriously in area below
specified altitude, because its mixture ratio is too lean,
output
drops
and the engine overheats for
operation
in
low
altitude area. In the case, askyour dealer to recover
the engine to its normal technical status.
