nuts are installed on the studs and hand-tighten before beginning the final torque sequence. Use an
alternating pattern to tighten each nut a little at a time. Do not over tighten the nuts. Only 5-7 foot
pounds of torque are required to secure and seal the carburetor base to the manifold. Once the nuts
are evenly torqued, check the carburetor linkage for smooth operation to wide open throttle, and then
closed again.
WARNING: Baseplates that are cracked during installation are not covered under warranty.

Connecting the Throttle Linkage
Get a helper for this part of the installation. Have someone sit in the car and hold the pedal firmly
against the floor. While holding the pedal firmly against the floor, pull the carburetor to its wide open
position (Fig. 8). Adjust the linkage rod or cable to the proper length, and then attach it to the
baseplate linkage. Remember, the pedal should come against a positive stop (the floor or an
aftermarket stop), just as the carburetor gets to wide open throttle. With the linkage rod attached to
the baseplate, make sure the carburetor can return to its closed position. Install your return spring(s),
and check again for smooth operation to wide open throttle, and then closed again. If you rely on the
baseplate linkage as a stop, it is possible to damage the linkage causing the throttle to stick in the
wide open position.
