ENGINE
The BEECHCRAFT Sundowner
C23 is
powered by a
Lycoming
O-360-A2G, 0-360-A4G, O-360-A4J, or 0-360-
A4K four-cylinder,
horizontally
opposed engine,
rated at
180
horsepower at
2700
rpm.
Normal operating
engine speed
range is
1800 to 2700 rpm
with a restricted
operating
range between
2150 and 2350
rpm,
for the 0-360-A2G
engine only.
ENGINE CONTROLS
The engine controls
are
centrally
located
for ease of opera-
tion from either the
left
or
right
seats. The throttle on the
power quadrant incorporates both a locking button and
a
vernier
arrangement
for fine
adjustments.
The
mixture
control
is locked with a clockwise
turn of the
friction nut lo-
cated
on the forward side
of
the
knob.
When
the
engine
controls
are installed in
the
pedestal
ar-
rangement,
the
levers are grouped
along
the
upper
face of
the
pedestal.
Their
knobs are shaped to
government
stand-
ard
configuration
so they
can be identified
by
touch. A
single
controllable
friction
lock on
the
right side of
the con-
sole permits manual adjusting
of the
pressure
on
the
levers.
