Walker Products 64-201 Carburetor Choke Diaphragm (Standard Replacement)

The Walker Products 64-201 Carburetor Choke Diaphragm is an OE Replacement component engineered to restore proper choke function in carbureted engines. These diaphragms are critical to the performance of vacuum-actuated choke systems, regulating the opening of the choke plate during cold starts and warm-up periods. A worn or leaking diaphragm can cause extended cranking, poor idle, stalling, or delayed choke opening—impacting overall engine drivability. Walker diaphragms are manufactured to match OE specifications for vacuum response, stroke travel, and fitment. Constructed with fuel-resistant materials that withstand the effects of ethanol-blended fuels, heat, and engine bay contaminants, these units are designed for long service life. With an exact OE fit, installation is straightforward and requires no modifications to the original carburetor housing. Walker Carburetor Choke Diaphragms are ideal for restorations, tune-ups, or maintenance of vintage and classic vehicles—providing smooth cold starts, stable warm-up operation, and dependable performance from startup to full operating temperature.
