What It Can Help Address

• Hard starting caused by incorrect choke thermostat operation
• Choke staying closed too long after cold start
• Choke opening too early and causing poor cold drivability
• Inconsistent carburetor warm-up behavior
• Service replacement needs on Rochester carburetor systems

Installation Notes and Tips

Verify the Rochester carburetor number and emissions configuration before ordering, since the catalog lists multiple engine and emissions-specific applications. Confirm the terminal style matches the existing connection: male blade with one terminal. Use the part number CV294 and the vehicle-specific notes to match the correct application.
