1957 Corvette: Field Service Bulletin: Throttle Return Spring Kit

Subject: Throttle Return Spring Kit
Model and Year: 1957 Chevrolet Corvette Fuel Injection 7014360
Source: Rochester Products Field Service Bulletin
Bulletin Number: B-F1-10
Date: 3/6/57



The throttle return spring was formerly attached to the air meter and the bell crank; to provide a better action, it is now attached between the throttle lever and bell crank stud.  For conversion of earlier units, kit No. 7014754 contains a new longer bell crank stud, a new throttle return spring, and a spring retainer to attach to the early throttle lever.  Since this is a design improvement only and does not affect performance, use of the kit is recommended only when it is necessary to replace the throttle return spring.
