and blocked AIR CLEANER ELEMENTS. Replace the air cleaner ele-
ments if necessary. Idle adjustment should be performed by your
Chevrolet Dealer.
If the above Fuel System checks and the checks suggested under
the Electrical System following do not correct the malfunction, it is
recommended that you turn to your Authorized Chevrolet Dealer
for further checks, adjustments or repairs.
ELECTRICAL SYSTEM
If, when the ignition key is turned to START, the engine will not
turn over, you have good reason to suspect electrical trouble.
(F) When there is no response at all to attempts to start the car,
check the obvious-your AUTOMATIC TRANSMISSION SELECTOR
LEVER must be in neutral position before the engine can be started.
Turning the IGNITION SWITCH rapidly back and forth several
times will sometimes correct a poor internal switch contact.
(G) The BATTERY may be discharged. If so, lights will be dim and
the horn will have a poor tone if it will blow at all.
Usually a garage recharge will be necessary to return the battery
to operotion. Occasionally, however, a long drive will recharge
the battery.
NOTE: If the battery is determined to be dead, and for no apparent
reason, have your Authorized Chevrolet Dealer check the
battery, the GENERATOR and the VOLTAGE REGULATOR.
GENERATOR trouble should already have been indicated by
the indicator on the instrument panel. Never remove generator
"BAT" lead without first disconnecting battery ground cable.

POOR BATTERY CONNECTIONS may be suspected if the car has
operated properly a short time before and now not even the horn
will operate. Check both ends of both battery cables. If the con-
nections are corroded, a car may sometimes be restored to opera-
tion by removing all cable ends, scraping all contacting surfaces
clean with a pen knife, and reassembling. If the cables are broken,
they must be replaced. The power supply should now be restored
unless the battery is dead.
(H)
If, however, the lights and horn work properly but the starter
will still not turn over, check the STARTER connections. A "click"
from the starter solenoid indicates that the wiring to the starter is
properly installed. If the wiring seems to be clean and tightly in-
stalled, the trouble is probably in the starter itself and should be
referred to your Authorized Chevrolet Dealer.
When the engine will "turn over" but will not start, the following
items may be checked along with Fuel System Checks listed
previously.
(I) With a clean dry cloth wipe the ceramic portions of the spark
plugs dry. In particularly damp or rainy weather dampness may be
the cause of not sta rting, especi-
ally when the engine is cold.
(J)
Check the cables at the top
of the distributor and coil as well
as each spark plug cable for
tightness.
(K)
If the car will still not start,
check for spark at the spark plugs
in the following manner:
Pull one of the spark plug
wires off its spark plug. Insert a
short piece of bare wire (such as
a bobby pin) between the rubber
