engine. Intermediate posltlons are
used
for

at
ahitudes
above
sea-level,
The
carbu-
retor
heat
control,
located
to the
left
of
the
thronle,
provides
maximum
carburetor
heat when
pul.led
to
its
full aft
position.
With
carburetor
heat
off,
all
eugine
air
passes
througtt
a
high-
efficiency
dry-type
filter.
Therefore,
prolonged ground
oper-
atlon with
carburetorheat"ON"
should be avoided,
particularly
on
unlmproved
ftelds
as the
alr is
not
flltercd.
STRUCTURES
All
structures are
of alumlnum
alloy
conatnrctlon
and are
