3. Replace all mounting nuts and washers. EnduraShine™ finish
carburetors should use the supplied 5/16” flat washers under any
other washers used. Hand tighten with a short box-end wrench,
alternating between diagonally opposed nuts.
CAUTION: Overtightening may break carb base and
void your warranty.
4. Connect all throttle and
transmission linkages and
throttle return springs. You
may have to cut, bend or
modify your stock throttle
cable brackets to fit the new
carburetor, or use GM
#352279
(See Fig. 8)
. 1972-
78 small-block Chevrolets may use Edelbrock Throttle,
Transmission, and Cruise Control bracket #8031, #8036, or #8030
(chrome).
IMPORTANT NOTE: With engine OFF, make sure that
there is no interference when opening and closing
the throttle. Be sure there is no binding or hanging
up between idle and wide open throttle, as this could
cause the throttle to stick open, resulting in loss of
engine speed control.
5. Manual choke:
Connect manual
choke cable to the
choke lever cable
mounting bracket
(See Fig. 9)
.
Electric choke:
Connect the red
choke wire to a 12
volt positive (+) source that is activated by the ignition switch
(Not
the coil or alternator; see Fig. 7)
.
NOTE: If manual choke is not connected (secondary carb of
dual-quad setup, for example) then the choke blade must be
fixed open. To lock open, use a stiff piece of wire between the
choke lever and the mounting bracket. Fold the wire to double
its thickness about one inch from one end. Insert the wire in
the choke lever, hold choke blade in the wide-open position,
and tighten the cable clamp on the folded end of the wire.
6. Connect all vacuum hoses to their proper location on the carburetor
(See Fig. 1). Replace hoses that appear brittle or cracked to prevent
vacuum leaks.
7. Connect fuel line to carburetor. Avoid contact with any sharp edges
or areas of extreme heat.
NOTE: Some late model Ford 460 engines are equipped with
hot fuel bypass units. It is necessary to replace the stock unit
with Ford #E3TZ9N176B (with blue dot) which has a .040”
orifice.
8. Edelbrock idle compensator #8059 may be installed to raise idle
speed during air conditioning compressor operation.
9. Install new air horn gasket and air cleaner stud (supplied). Install air
cleaner, making sure it does not contact the carburetor linkage or
fuel line, and has proper hood clearance. We recommend Edelbrock
Pro-Flo chrome air cleaner #1221, which is a 14” diameter, open
element air cleaner that is designed to fit all Edelbrock Performer
Series carburetors. Extremely
low profile air cleaners will not fit
electric choke carburetors
without air cleaner spacer #8092
(due to choke and fuel line
interference) but will fit manual
choke carburetors when used
with 90° banjo fuel inlet fitting
#8089
(See Fig. 10)
.
10. Mark air cleaner stud for
proper length, remove
from carburetor, and cut
with a hacksaw. Deburr
stud and reinstall it in the
carburetor, along with the
air cleaner
(See Fig. 11)
.
11. Recheck all linkage for
smooth throttle operation.
12. Reconnect the negative battery cable from the battery.
13. Start engine and check for fuel or vacuum leaks. With engine at
normal operating temperature and the choke fully open, set idle
speed and mixture screws (See Carburetor Owner’s Manual).
CAUTION: Be alert to carburetor flooding. Flooding can be
caused by dirt, small particles of hose cuttings, floats and inlet
needles which have settled during shipping, etc. When the fuel
pump is turned on or when the engine is first started, watch
closely for signs of flooding. If flooding occurs, turn engine off
immediately and lightly tap on the side of the carburetor that is
flooding, in the rear needle and seat area with a rawhide
mallet, or wooden handle of a hammer. Start engine and see if
flooding continues. If so, refer to your owner’s manual.
WARNING: NEVER POUR FUEL DIRECTLY DOWN THE
CARBURETOR WHEN ATTEMPTING TO START THE
ENGINE! THIS MAY CAUSE A BACKFIRE AND POSSIBLE
ENGINE COMPARTMENT FIRE, RESULTING IN ENGINE OR
VEHICLE DAMAGE, PERSONAL INJURY, AND/OR DEATH.
