Borg Warner VC430 Choke Pull-Off – Automatic Choke Diaphragm For Carbureted Engines

This is the Borg Warner VC430, a choke pull-off (also called a choke break diaphragm). It's a small but important part for older cars and trucks with carbureted engines. Its job is to automatically pull the choke plate open a little bit once the engine starts, letting in more air so the engine doesn't run too rich and stall. If your vehicle is hard to start when warm, stalls after starting, or gets poor gas mileage, a faulty choke pull-off might be the culprit. This is a direct replacement VC430 unit. It comes as one part. Package dimensions are about 6x4x3 inches. A classic repair part for vintage automotive restoration or maintenance.
