8. If the vehicle requires other linkage hardware, such as automatic kickdown linkage stud, remove the stud from the original carburetor and
install it in the appropriate place on the throttle lever.
9. Install the carburetor flange gasket on the intake manifold.

10. Place the carburetor on the manifold. Open the throttle and check to assure that the throttle plates do not interfere in any way with the
manifold. A lip resulting from manifold bores, which are smaller than the carburetor bores will disturb cylinder-to-cylinder distribution,
restrict airflow, and result in compromised performance. If necessary, have the manifold bores machined to the same diameter as the
carburetor throttle bores.
11. Install the carburetor holddown nuts and snug nuts progressively in a “criss-cross pattern” (Fig. 3). Tighten each nut twice. WARNING:
Over-tightening may result in warped or cracked throttle bodies and/or binding throttle action resulting in an unstable return-to-idle.
12. Reconnect the throttle and transmission kickdown linkage or throttle return spring. Operate the linkage from inside the vehicle or have
someone check to assure complete opening of the carburetor throttle plates.
WARNING: Check the assembled linkage for sticking and/or binding throttle action. Any sticking, binding, or other interference in the throttle
linkage could result in uncontrolled engine speed.
NOTE: If this carburetor is being installed along with an intake manifold on a vehicle, which was originally equipped with a 2BBL induction
system, it will probably be necessary to purchase a throttle cable mounting bracket. This should come from a 4BBL engine of the same
engine family in order to provide proper mounting and operation of the throttle cable and other linkage.
