The carburetor is also finished with a polished chrome plating, which not only looks great but also provides an additional layer of protection against the elements.

Installing the SU 465R HS4 carburetor on a 1971 MGB involves removing the stock carburetor and intake manifold, and replacing them with the new components.

3. Cold Starting: Carburetors can be difficult to start in cold weather, which is a common issue for classic cars.

4. Maintenance: Regular maintenance is essential to keep the SU Carburetor functioning properly, which can include tasks such as adjusting the idle mixture, synchronizing the carburetor, and replacing worn parts.
