The
Teledyne
Walbro
carburetor
can
be
equipped
with
an
adjustable
main
jet
for
high-altitude
operation
(above
4000
ft.).
Minor
adjustment
will
be
necessary
for
proper
operation
at
a
particular
altitude.
Whenever
a

adjust
ment
is
deemed
necessary,
see
Figure

and
proceed
as

fuel,
making
the
air-fuel
mixture
richer.

locking
nut
(22).
IMPORTANT
Restricting
the
fuel
