Throttle Cable

The Holley 1920 and the Carter BBS used all the same throttle and kickdown linkage parts. If your throttle won't open all the way, it's because of one or more of the following:

• Your kickdown linkage is hitting the exhaust pipe or some other obstacle

• Your kickdown linkage is not adjusted properly (too long)

• Your carburetor-to-intake gasket is too thin (carb sitting too low, effectively making the kickdown linkage too long)

There's nothing the matter with the factory-type kickdown linkage (though the '69-up setup is safer, because if something snags the kickdown linkage it won't pull the throttle open as on the '68-down setup). If yours is faulty or missing pieces, I don't recommend futzing with Lokar. See this thread for kickdown options.
