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, #8030 (chrome)
or #8032 for Vortec/E-Tec applications.
NOTE: Transmission Cable Adapter #8026 - Required for all Edelbrock/
Carter AFB Carburetors when using the following Transmission: GM
700R4/2004R, 4L60.
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. Make sure choke is open before testing.

5.
Manual choke: Connect manual choke cable to the choke lever
cable mounting bracket (See Fig. 9).
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 on page 3). 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 cleaner 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 and Thunder Series
AVS 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).

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).
NOTE: Running without an air cleaner is strongly discouraged for a
street-driven vehicle. Dirt and varnish will accumulate in critical bleeds
and upset the fuel metering. Dirt and debris may easily get into the fuel
bowl through the bowl vents or larger bleeds and cause a multitude
of problems.
