Sierra Choke Pull-Off 18-7667, Replaces 1397-8582, for Rochester 4V Carburetors

The Sierra 18-7667 is a choke pull-off built for Rochester 4V carburetors. In these carburetor systems, the choke pull-off is the component that reacts to intake vacuum and pulls the choke plate open to the correct partial-open position once the engine starts, preventing an overly rich mixture during warm-up. As the engine and carburetor age, a worn or leaking choke pull-off diaphragm can cause hard starting, stalling, black smoke, or a choke that stays closed too long (or opens too soon), so replacing it with a properly matched unit restores correct choke plate timing and smoother cold starts.

The Sierra 18-7667 is manufactured to fit Rochester 4V carburetors and directly replaces OEM number 1397-8582. It is sold as a single choke pull-off unit and installs in place of the original component using the existing carburetor mounting points.
