Warm-Up
Always let the engine idle for 20
to 30 seconds after starting and
drive at moderate speeds for several
miles, especially during cold
weather.

Know About Gasoline
Mileage and How to
Improve It
How you drive, where you drive,
and when you drive
all have an
effect on how many miles you can
get from a gallon of gasoline. The
careful attention you give your car
as far as maintenance and repairs
are concerned will also contribute
importantly to fuel economy.
Fuel Selection
Your vehicle is designed to op­
erate on unleaded or low-lead fuels

terioration. Your engine does not
require premium fuel. Therefore,
its use would be an unnecessary
additional expense.
If the service
station gas pump has a symbol similar
to the following, use
un­
leaded or low-lead gasoline with a
symbol of 2. A higher number
is
satisfactory but not required.
"Jackrabbit" Starts
Gasoline can be conserved (and
engine and tire life prolonged) by
avoiding unnecessarily rapid
ac­
celeration away from lights and
stop signs.
Stop-And-Start Driving
Frequent stops and starts during
a. trip really cut down on your
64
miles per gallon. Plan even your
short shopping trips to take
advan­
tage of through streets to avoid
traffic lights.
Pace your driving like
the professional drivers to avoid
unnecessary stops.
Speed Versus Mileage
Excessive speed on the highway
raises your gas consumption
dras­
tically. Statistics prove that you
might save
as much as 19% on
your fuel bill by driving
50 MPH
instead of 70 MPH.
Excessive Idling
An idling engine uses gasoline,
too, (especially after a cold engine
start).
If you're faced with more
than a
few minutes wait you're
better
off to "turn off" and start
again later.
Sudden Stops

If the ignition switch will cause the engine to "turn over" or "crank" but the car will not start, check Steps A through 0 below. NOTE : If continual "flooding" of the carburetor is evidenced by a carburetor wet with
fuel or black exhaust smoke,
perform the operation sug­
gested in paragraph D only .
(A) The first and most obvious, and one of the most frequently Checking Fuel Flow
67
overlooked, items to check when you have difficulty in starting your car is the 'amount of fuel in the tank. Make it a habit to check the FUEL GAUGE regularly and most especially at a time when the engine will "turn over" but will not start.
(B) If the fuel tank is not empty, you may check further to see whether the fuel is reaching the carburetor. Disconnect the fuel line at the carburetor and remove the center wire (ground the secondary coil terminal or disconnect the primary wire from the coil to the
distributor at the coil) from the coil tower. Place a jar or cup under the open line and briefly "crank" the engine by means of the starter. If fuel spurts from the fitting, you may assume that the FUEL LINES are clear and the FUEL PUMP is operating properly. If no fuel leaves the line, either the fuel
lines or fuel pump are at fault ,
See your Authorized Chevrolet
Dealer.
(C) Before reconnecting the fuel
line
to the carburetor, remove the
FUEL FILTER from the carbu retor
inlet and check its condition . If it
appears to be clean, replace it
and reconnect the fuel line. Re­
place the filter if it appears to be plugged.

the problem may be: an EMPTY CARBURETOR BOWL caused by a "stuck shut" carburetor; a FLOODED CARBURETOR caused by a "stuck open" condition and evidenced by gasoline seeping around and down the outside of the carburetor; or a stuck CHOKE valve. Remove the air cleaner from the carburetor. Check that the choke
