The Venturi B1271-10 B-4 is a high-performance carburetor designed for applications requiring superior fuel delivery and engine response. This carburetor is part of Venturi's B-4 series, which is known for its advanced features and precise adjustability.

The B1271-10 B-4 carburetor features a unique venturi shape, which provides excellent atomization of the fuel mixture for optimal combustion. The venturi throat diameter is 10mm, making it suitable for engines with moderate power requirements. The carburetor comes with four 1.5-inch (38mm) SU-style float bowls, which ensure consistent fuel delivery to the engine.

One of the standout features of this carburetor is its adjustability. It comes with a total of 11 jets, including four main jets and seven needle jets, allowing for precise tuning of the fuel mixture.

This regulator maintains a consistent fuel pressure of 5.5 to 6.5 psi, ensuring optimal fuel delivery to the engine. The regulator can be easily set using the adjustment screw located on the bottom of the carburetor.

The B1271-10 B-4 carburetor also comes with a number of other performance-enhancing features. These include a vacuum secondary circuit, which provides additional fuel during vacuum conditions for improved engine response, and a built-in fuel pressure relief valve, which prevents fuel surge during rapid acceleration.

The carburetor housing is made of high-quality cast aluminum, which is both lightweight and durable. The carburetor also comes with a chrome-plated float bowl gasket, which provides a good seal and adds a touch of aesthetic appeal.

In summary, the Venturi B1271-10 B-4 carburetor is a high-performance carburetor that offers superior fuel delivery, adjustability, and durability. Its unique venturi shape, adjustable jets, and built-in fuel pressure regulator make it an excellent choice for applications where precise tuning and optimal engine response are required.
