Fuel
Mixture
Leaning
Procedure.
Improper
fuel/air
mixture
during
flight
is responsible
for
many
engine
problems,
particularly
during
take-off
and
climb
power
settings.
The
pro-
cedures
described
in
this
manual
provide
proper
fuel/air
mixture
when
lean-
ing
Textron
Lycoming
engines;
they
have
proven
to be
both
economical
and
practical
by
eliminating
excessive
fuel
consumption
and
reducing
damaged
parts
replacement.
It is
therefore
recommended
that
operators,
of
all
Tex-
tron
Lycoming
aircraft
power-plants,
utilize
the
instructions
in
this
publica-
tion
any
time
the
fuel/air
mixture
is adjusted
during
flight.
Manual
leaning
may
be
monitored
by exhaust
gas
temperature
indica-
tion,
fuel
flow
indication,
and
by
observation
of engine
speed
and/or
airspeed.
However,
whatever
instruments
are
used
in leaning
the
mixture,
the
following
general
rules
should
be
observed
by
the
operator
of Textron
Lycoming
aircraft
engines.
GENERAL
RULES
Never
exceed
the
maximum
red
line
cylinder
head
temperature
limit.
For
maximum
service
life,
cylinder
head
temperatures
should
be
main-
tained
below
435°F.
(224°C.)
during
high
performance
cruise
operation
and
below
400°F.
(205°C.)
for
economy
cruise
powers.
On
engines
with
manual
mixture
control,
maintain
mixture
control
in
"Full
Rich"
position
for
rated
take-off,
climb
and
maximum
cruise
powers
(above
approximately
75%).
However,
during
take-offfrom
high
elevation
air-
port
or during
climb,
roughness
or loss
of
power
may
result
from
over-richness.
In such
a case
adjust
mixture
control
only
enough
to
obtain
smooth
opera-
tion
- not
for
economy.
Observe
instruments
for
temperature
rise.
Rough
opera-
tion
due
to over-rich
fuel/air
mixture
is
most
likely
to be
encountered
at
altitudes
above
5,000
feet.
Always
return
the
mixture
to full
rich
before
increasing
power
settings.
Operate
the
engine
at
maximum
power
mixture
for
performance
cruise
powers
and
at
best
economy
mixture
for
economy
cruise
power;
unless
other-
wise
specified
in the
airplane
owners
manual.
