Standard Motor Products CV234 Carburetor Choke Thermostat

The Standard Motor Products CV234 Carburetor Choke Thermostat is a precision-engineered replacement component designed to regulate the air-fuel mixture in carbureted engines during cold starts and warm-up cycles. This critical component automatically controls the carburetor's choke valve operation, ensuring optimal engine performance from startup through warm-up.

How It Works:

The CV234 features a bi-metallic coil spring that responds to temperature changes to control choke valve position. When the engine is cold, the thermostat keeps the choke valve closed, restricting airflow to create a richer fuel mixture necessary for reliable cold starts. As the engine warms up, the thermostat gradually opens the choke valve, allowing more air into the carburetor to achieve the proper air-fuel ratio for normal operating conditions.

Key Features:

• OE-quality construction ensures reliable, long-lasting performance
• Precision-calibrated bi-metallic spring for accurate choke control
• Direct replacement for worn or failed original equipment
• Eliminates common cold-start issues including hard starting, rough idle, and hesitation
• Manufactured by Standard Motor Products, a trusted name in automotive parts since 1919

Standard Motor Products backs this component with a 36-month warranty, demonstrating their confidence in quality and durability. When your carburetor choke thermostat fails, symptoms may include difficulty starting when cold, engine stalling during warm-up, excessive fuel consumption, or the choke valve remaining closed after the engine reaches operating temperature. The CV234 restores proper automatic choke operation for smooth, reliable performance.
