Smooth out cold-start and warm-up drivability with the Walker Products Carburetor Choke Pull-Off 101-726, a vacuum-actuated device that controls the timed opening of the choke plate after the engine fires. It installs as a direct-fit replacement for 1972 Chevrolet, GMC, and Checker models equipped with the V8-5.7L engine — including the Chevrolet Camaro, Corvette, Chevelle, Nova and C10 Pickup, plus the GMC Jimmy — with the complete list in the "Vehicles it fits" section.
As the engine warms, the pull-off uses engine vacuum to gradually open the choke plate. If a failed pull-off is the cause of rich running, stalling, or rough idle during warm-up, this unit replaces it and restores that function.
- OE-replacement design: matched to original-equipment specifications for vacuum response, stroke travel, and mounting configuration.
- Brass construction: built to withstand fuel vapors, heat, and engine vibration.
- Controls choke plate opening: regulates choke release after cold start for a smoother warm-up.
- Two mounting bolt holes and a single vacuum port: designed to match the factory carburetor and install without modification.
