causing spark plug overheating and
pre-ignition.
Clean the electrode surfaces with
a small file (Fig.
6) .
Dress the elec-
trodes to secure fiat parallel sur-
faces on both the center and side
electrode.
After cleaning, examine the plug
carefully for cracked or broken in-
sulators, badly pitted electrodes, and
other signs of failure. Replace as re-
quired.
INSTALLATION
1. Install the spark plugs and
torque each plug to 15-20 ft-lbs.
When a new spark plug is installed
in a new replacement cylinder head,
torque the plug to 20-30 ft-lbs.
2. Connect the spark plug wires.
Push all weather seals into position.
REPLACE FUEL FILTER
A replaceable fuel filter is located
between the fuel pump and the car-
buretor fuel inlet line (Fig.
8) .

8-Fuel Filter
REPLACEMENT
1. Disconnect the fuel line from
the filter. Unscrew the filter from
the fuel pump.
2. Screw the new filter into the
fuel pump. Do not over-tighten it.
Connect the fuel line to the fuel
filter. Use a wrench on the filter
connection to prevent it from turn-
ing when connecting the line.
3. Operate the engine and check
the fuel line and filter connections
for leaks.
ADJUST ACCELERATING
PUMP LEVER
OPERATING ROD
1. With the accelerating pump op-
erating rod in the top hole (long
pump stroke) of the pump arm and
TO ADJUST, BEND HERE AS NECESSARY

the throttle plates closed, measure the
distance from the top surface of the
air horn to the top of the plunger
shaft (Fig.
9) .
The distance should
be within specification.
2. To adjust the distance, bend the
accelerating pump operating rod at
the existing lower bend, as neces-
sary (Fig. 9).
PUMP STROKE
The accelerating pump stroke ad-
JUStment compensates for the fuel
needs of the engine during extremes
of hot or cold temperature. Insert
the accelerating pump operating rod
into the appropriate hole in the
pump arm for the climate in which
the car is to be driven (Fig. 9).
REPLACE ENGINE COOLANT
1. Remove the radiator cap slowly.
Sudden release of the pressure will
cause "false boiling" and ejection
of coolant. Open the radiator drain
cock and remove the cylinder block
drain plugs to drain the cooling sys-
tem.
2. Clean or flush the cooling sys-
tem, if required.
To fill the cooling system:
1. Close the radiator petcock and
11941-A
install the cylinder block drain plugs.
Move the heater control dial indi-
cator clockwise to the "MAX" heat
zone.
' 2. Fill the system with coolant to a
point one inch below tlie bottom of
the supply tank filler neck.
Install the pressure cap and turn
it clockwise until the first stop is
reached. This will allow the cooling
system to vent entrapped air into
the atmosphere. Do not tighten the
cap fully.
3. Operate the engine until normal
operating temperatures are reached.
After the initial fill, the coolant
level drops due to the displace-
ment of entrapped air. Add more
coolant to fill the supply tank to the
required level. Tighten the pressure
cap.
4. Check the cooling system for
leakage. Move the heater control dial
indicator to the "MIN" heat zone.
Turn the ignition key to the "OFF"
position.
CHECK ENGINE
COOLANT LEVEL
The coolant level should be kept
1 inch below the bottom of the filler
neck.
