the low setting. New points should
be set to the low contact because the
rubbing block will wear down sl ight-
ly
whi le seating to the cam.
Leave the distributor on the test
set until after Operation No. 21 has
been performed.
21. C heck and Adjust Distributor
Spark Advance. Refer to the pro·
cedure for the applicable eng ine in
Part 2-1.
After the spark advance has been
checked and adjusted, install the
du st cover if applicable and the rotor
and install the distributor in the
block. Install the distributor cap. In -
sert each distributor wire in the
proper d istribut or cap socket. Be
sure the wires are forced all the way
down into their sockets. The No. I
socket is identified on the cap. Start-
ing at the No. 1 socket, install the
wires in the direction of distributor
rotation (clockwise on the 223 Six
and counterclockwise on V-S en-
gi nes) in the firing order (1-5-3-6-2-4
on the 223 Six and 1-5-4-S·6·3-7-2
on all V-S engines). Push all weather
seals into position .
22. Perform a Spark Intensity
Test of Each Spark Plug Wire.
C heck the spark intensity of one wire
at a time. Install a terminal adapter
in the terminal of the wire to be
checked. Hold the adapter approxi-
mately
%0
inch from the exhaust
manifo ld and c rank the engine wi th
a remote starter switch. The spark
shou ld jump the gap regularly.

MECHANICAL FUEL PUMP.
Disconnect the fue l line at the car-
buretor. Install a pressure gauge (0-
15 psi) and a petcock between the
gauge and the carburetor fue l inlet
line. Vent the system, by opening the
petcock momentarily, prior to taking
a pressure reading. Operate the en-
gine at the specified rpm. After the
pressure has stabilized it sho uld be
with in specifications (Tab le 3).
Operate the engine at 500 rpm.
Open the petcock and expel the fue l
inlo a suitable container. Observe the
time required to expe l one pint. It
shou ld be within specifications (Table
3).
ELECTRIC FUEL PUMP.
Disconnect the fue l line at the car-
buretor.
Using
1,.4
-inch pipe fillings, install
a pressure ga uge (0-15 ps i), then a
!.4
-inch gate valve to the carburetor
fuel in let line.
lnstall a flexible hose in the gate
valve so that the fuel can be expell ed
into a suitable co ntainer. Use of
smaller than lA -inch fittin gs will re-
slri ct the fue l flow.
Operate the fue l pump with the
primer switch. Ad just the gate va lve
to obtain the specified pressure (Table
3). Expel the fue l into a suitab le con-
tainer. Engage the primer switch and
observe the time required to expel
o ne pint. Refer to T ab le 3 for the
correc t spec ifications.
If the fuel flow is be low spec ified
requirements, check the fue l pump
at the outlet in the tank . This check
w ill establ ish whether there is a re-
str iction in the fuel line or the fuel
pump is defect ive. At the fue l tank
outlel, the fuel pump pressure and
capacity shou ld be within specifica-
tions (Table 3).
WHILE ENGINE IS
WARMING UP
Place the transmiss ion selector
lever in neutral position and set the
parking brake. Start the engine and
opera te it at 1200 rpm for 30 rnin~
utes to stab ilize engine temperatures.
Whi le the eng ine is warming up, per-
form the following operations:
24. Clean Carburetor Air C leaner
DRY TYPE. Direct compressed
air against the element in the oppo-
site direction of normal air flow, that
is, from th e inside of the fi lter out.
Clean the air cleaner body and
cover in c leaning solvent, then wipe
dry.
Do not install the air clea ner at
this time.
OIL BATH. Remove the air
cleaner from the carbu retor. Remove
the cover a nd dra in the oil from the
reservoir. Wash all the air cleaner
parts in a suitable cleaning solvent.
Dry them with compressed air.
Inspect the gasket between the oil
reservoir chamber and cleaner body
and replace it if necessary.
Saturate the filter element and fill
the oil reservo ir to the indicated level
with the recommended viscosity en-
gine oi l (Group 16).
Do not install the a ir cleaner at
this time.
25. Replace Dry - Ty p e Ai r
C leaner E lement. Remove the air
cleaner from the carburetor and re-
move the element from the air
cleaner body. W ash the air cleaner
body and cover in so lvent and wipe
them dry. I nsert a new filter element
in the air cleaner body. Do not in-
stall the air cleaner at this tim e.
26_ C heck and Adj ust Ignition
Timing. On a Loadomat ic or a dual
advance distributor, disconnect the
distributor vacuu m line.
Connect the tim ing light hi gh ten-
sion lead to the No. I spark plug and
the other two leads of the timing
light to the battery terminals. Do not
