1. Apply the foot brake.
2. Place transmission selector
in "P" or "N" (UP" preferred).
A starter safety switch prevents
starter operation while the trans
mission selector
is in any drive
position.
(If it is necessary to
re-start the engine with the car
moving, place the selector lever
in
"N".)
3. Depress accelerator pedal and
activate starter
as outlined be
low for different conditions.
• Cold Engine -Fully de
press
accelerator pedal and
slowly release.
With foot off
the pedal,
crank the engine
by turning the ignition key
to the Start position-release
when engine starts.
If engine starts, but fails to
run, repeat this procedure.
When engine is running
smoothly, the idle speed may
be reduced by slightly de
pressing the accelerator pedal
and then slowly releasing.
• Warm Engine -Depress ac
celerator
pedal about halfway
and hold while cranking the
engine.
• Extremely Cold Weather
(Below
0° F.) Or After Car
Has Been Standing Idle
Several
Days-
Fully depress and release
accelerator pedal two
or three
times before cranking the
engine.
With foot off the ac
celerator pedal,
crank the
engine by turning the key to
the Start position and release
when engine starts.

1. Apply parking brake and shift
transmission to neutral.
2.
Hold clutch pedal to floor
throughout the starting proce
dure. A starter interlock pre
vents starter operation when
clutch
is not fully depressed.
3.
Operate accelerator pedal and
starter
as outlined in step 3
(under Automatic Transmission
Models).
Engine Flooded
Depress accelerator pedal and
hold to floor while starting until
engine
is cleared of excess fuel
and
is running smoothly. Never
"pump" the accelerator pedal.
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.

The following chart will serve as
a guide for selecting the proper oil
viscosity. The
proper viscosity helps assure
good cold and hot starting by re
ducing friction and thus increasing
cranking speed.

Engine Tune-Up, Emission
Control and Electrical
System Checks
Fuel and electrical systems are
subject to wear and contamination
and require periodic cleaning and
adjustments to maintain maximum economy
and performance. Proper
adjustment of carburetor idle
speed, engine timing and dwell, and
operation of the Positive Crankcase
Ventilation Valve
(PCV) are im
portant to control hydrocarbon
and
CO emissions within govern-
54
ment legislated levels. These ad
justments should be made at the
first oil change
(4 months or 6,000
miles, whichever occurs first). The
above fuel and electrical system
checks also are included in engine
tune-ups which are recommended
at one year or 12,000-mile inter
vals.
Air Injection Reactor (A.I.R.)
The Air Injection Reactor sys

Downloaded from www.Manualslib.com manuals search engine The chart on the previous page, and the information on the pages
which
follow, contains information designed to aid the average
driver to discover, and possibly correct, conditions resulting in minor
mechanical
difficulties in his car. The chart, designed to point out
possible solutions to several of the most common automotive mal
functions and point out a logical checking sequence, will lead step
by step to the most likely causes and corrective procedures. If, after
making the checks and adjustments suggested, the source of the
trouble has not been found and corrected, it is strongly recom
mended that an Authorized Chevrolet Dealer inspect the vehicle and
make whatever repairs
or adjustments are necessary.
FUEL SYSTEM AND ENGINE
If the ignition switch will cause the engine to "turn over" or
"crank" but the car will not start, check Steps A through D below.
NOTE:
If continual "Rooding" of the carburetor is evidenced by a
carbur.tor wet with
fuel or black exhaust smoke, perform the
operation suggested in paragraph D only.
(A) The first and most obvious,
and one of the most frequently overlooked, items to check when
you have difficulty in sta rting you r 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.
(8)
If the fuel tank is noi empty,
you may cheek further to see Checking Fllel Flow
69
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 "cronk" 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 carburetor
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.
(D) If the fuel seems to be
reaching the
carburetor properly, File' Fllt.r
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 valve moves freely and is not stuck. (Don't mistake normal spring
tension for a stuck valve.) Tap the side of the carburetor sharply
several times with a light tool such as a screwdriver handle or pliers. Replace the air cleaner and attempt to start the engine in
the
normal manner.
