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 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 "f/ooding" of the carburetor is evidenced by a
carburetor 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 starting your
ca r 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.
(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. 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 Au-
thorized 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. 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. Replace the
filter with a new one as soon as possible.
Fuel Filter
(0) If the fuel seems to be reaching the carburetor properly, the
problem may be a FLOOD.ED 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 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.
