MINOR TROUBLE SHOOTING PROCEDURES
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 fourld 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 0 below.
NOTE;
If continual "flooding"
of
the carburetor
is
evidenced by
a
carburetor wet with fue/ .or black exhaust smoke, perform the
operation suggested
in
paragraph 0 only.
(A)
The first and most obvious,
and one of the most frequently
overlooked,
items
to check when
you have difficulty in starting your
ca~
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 en-
gine will "turn over" but will not
start.
(8)
If the fuel tank is not empty,
Checking Fuel
Flow
42
you may check further to see whether the fuel is
reaching
the
carburetor
.
Disconne.cl the fuel lines at the carburetors. Place a
jar or cup under each open line and br·iefly
"crank" the
engine by
means of the starter. If fuel spurts from the fittings, you may assume
that the FUEL LINES are clear and the .FUEL PUMP is operating
p·roperly.
If
no fuel leaves the lines, either the fuel lines or fuel
pump are at fault
.
See your Authorized Chevrolet Dealer.
(C)
Before reconnecting the fuel lines to the carburetors, remove
the FUEL FILTER from one carburetor inlet and check its condition
.
If it appears to be clean,
replace
it and reconnect the fuel lines
.
If
the filter appears to be plugged, clean it as well as possible by
scraping out the foreign material and cleaning in a solvent. Then
reinstall the filter and repeat the procedure with the second carbu-
retor. Replace the filters with new ones as soon as possible.
(0)
If the fuel seems to be reaching the carburetors properly, the
problem may be: an EMPTY CARBURETOR BOWL caused by a
.
"stuck
shut" carburetor or a FLOODED CARBURETOR caused by a
"stuck
open" condition and evidenced by gasoline flowing down
the outside of the carburetor; or a stuck CHOKE valve
.
Remove the
air cleaners from the carburetors
.
Check that the choke valves
mov.
e
freely and are not stuck_ Tap the side of the carburetors sharply
several times with a light tool such as a screwdriver handle or pliers
.
R~place the air cleaners and attempt to start the engine in
the
normal manner.
(E)
If the car will start but stalls when hot or has a rough idle,
you can suspect a faulty IDLE ADJUSTMENT, or extremely dirty
