Carburetor Choke Thermostat

Description

Walker Products Carburetor Choke Thermostats are OE Replacement components engineered to restore accurate choke plate movement during cold start and warm-up conditions in carbureted engines. These thermostats use a calibrated bi-metallic spring to sense engine heat and gradually open the choke plate, allowing smooth transitions from cold idle to normal operation. A failed or sluggish choke thermostat can cause hard starts, rough idle, or poor fuel economy—especially in older vehicles. Each Walker choke thermostat is designed to match OE specifications for thermal response rate, spring tension, and rotational travel to ensure consistent choke release under real-world conditions. Built with heat-resistant materials to withstand engine bay temperatures and fuel vapor exposure, these units are durable and reliable for long-term service. Designed for an exact OE fit, they install easily in the original mounting location using factory brackets and connections. Whether replacing a failed unit or performing a full carburetor system restoration, Walker Choke Thermostats help deliver smooth cold starts, reduced emissions, and reliable engine performance.
