Review STROMBERG Vis a gas Carburetor Chevrolet Wood Crate Box Rat Rod fits 1928

The Stromberg A-12021 Vis-a-Gas carburetor is a classic fuel delivery system that adds an authentic touch to your 1928 Chevrolet wood box rat rod. This carburetor is not just a component that ensures the smooth running of your engine; it is a statement piece that adds character and charm to your vintage hot rod.

The Stromberg A-12021 is a single-barrel carburetor, which means it feeds air and fuel into the engine through one barrel. The Vis-a-Gas designation refers to the built-in fuel pressure regulator, which maintains a consistent fuel pressure for optimal engine performance.

The body of the carburetor is made of high-quality aluminum, which not only gives it a classic look but also makes it durable and lightweight. The finish on the carburetor is polished to a high sheen, which adds to its visual appeal. The top of the carburetor features a chrome venturi plate, which not only looks great but also helps to maintain a consistent air-fuel mixture for efficient combustion.

The Stromberg A-12021 comes with a set of adjustable jets, which allow you to fine-tune the carburetor for your specific engine and driving conditions. The needle and seat assembly can be adjusted to change the fuel mixture, while the idle mixture screw allows you to set the carburetor for optimal idle speed and quality.

One of the unique features of the Stromberg A-12021 is the automatic choke. This system uses a vacuum-operated mechanism to provide rich fuel mixtures during engine start-up, ensuring easy starting in cold conditions. The choke can be easily engaged and disengaged using the lever on the side of the carburetor.

The Stromberg A-12021 Vis-a-Gas carburetor is a high-performance component that is perfect for your 1928 Chevrolet wood box rat rod. It not only provides reliable fuel delivery but also adds to the visual appeal of your vintage hot rod.
