Review MIKUNI Solex 1981 8283 Chry. Colt champ 1400cc 2/4 W. Drive fits COLT

Introducing the Mikuni 64-9631 carburetor, a high-performance solution designed specifically for the Chrysler Colt and Champ models produced between 1981 and 1983 with a 1400cc 2/4 drive engine. This carburetor is a direct upgrade from the original SOLEX unit, offering superior fuel delivery and engine response.

The Mikuni 64-9631 is a double-barrel carburetor, meaning it consists of two separate barrels for improved fuel distribution and airflow. Each barrel is equipped with a 34mm Mikuni VM34 bore size, ensuring optimal fuel delivery for the engine's power requirements.

One of the most notable features of the Mikuni 64-9631 is its advanced idle circuit, which allows for precise engine idling and improved drivability. The idle circuit operates using a separate jet and needle, allowing for fine-tuning of the idle mixture for various driving conditions.

Another significant advantage of this carburetor is its vacuum secondary system. This system utilizes a secondary throttle valve that opens under vacuum, allowing for a more efficient fuel-air mixture during acceleration and engine load. This results in increased horsepower and torque, providing a noticeable improvement in engine performance.

The Mikuni 64-9631 carburetor also boasts a high-quality construction, with a durable cast aluminum body and brass components. The float bowls are designed with a large capacity to minimize the need for frequent refueling, and the carburetor is equipped with easily accessible adjustment screws for fine-tuning the fuel mixture.

In summary, the Mikuni 64-9631 carburetor is an excellent upgrade for the Chrysler Colt and Champ models with a 1400cc 2/4 drive engine. It offers superior fuel delivery, improved engine response, and increased power through its advanced idle circuit and vacuum secondary system. With its high-quality construction and easy adjustability, the Mikuni 64-9631 is an excellent choice for those seeking to enhance the performance of their classic Chrysler vehicle.
