Review SU Carburetor Fzx 1146 Austin Morris British Leyland Nice Used For Rebuild fits HS2

The SU FZX-1146 carburetor is a classic component of Austin Morris British Leyland vehicles, specifically designed for use in various models. This carburetor is a monobloc, single-barrel design, which ensures efficient fuel delivery to the engine.

The FZX-1146 model features a downdraught configuration, which means the carburetor is mounted below the intake manifold. This design is ideal for engines that require a low-mounted carburetor to maintain adequate clearance between the fuel delivery system and other engine components.

The carburetor comes with a 1.75-inch (44.45mm) venturi, which is suitable for engines with a moderate power output. The venturi shape and size are crucial in determining the airflow and fuel mixture that enters the engine's combustion chamber. A well-designed venturi ensures optimal engine performance, including efficient fuel consumption and strong throttle response.

The SU FZX-1146 carburetor is equipped with a synchronous distributor, which helps maintain the correct ignition timing for each cylinder in the engine. This distributor is connected to the carburetor via a drive gear, allowing the engine to run smoothly and evenly.

The carburetor body is made from high-quality cast aluminum, ensuring durability and resistance to corrosion. This material choice is essential for prolonging the life of the carburetor, especially in vehicles that are frequently exposed to harsh environmental conditions.

The FZX-1146 carburetor comes with adjustable jetting, allowing users to fine-tune the fuel mixture for various driving conditions and engine performance requirements. This feature is particularly useful for those looking to optimize their vehicle's fuel efficiency, power output, or emissions.

In summary, the SU FZX-1146 carburetor is a reliable and durable component for Austin Morris British Leyland vehicles. Its downdraught design, monobloc construction, and synchronous distributor make it an efficient and effective fuel delivery system. Additionally, its adjustable jetting feature provides users with the flexibility to customize the carburetor's performance for their specific driving needs.
