Review ZENITH Wisconsin Carburetor

The Zenith 15320 VG4D Wisconsin Carburetor is a high-performance, vacuum-secondary carburetor that is widely used in various applications, particularly in aircraft engines and vintage automobiles. This carburetor is a four-barrel, downdraft type, which means that the intake runners are positioned below the main body of the carburetor.

The VG4D model is known for its advanced features that ensure optimal engine performance under various conditions. One of its most notable features is the vacuum-secondary system, which utilizes a vacuum diaphragm to provide additional fuel to the engine under full throttle or high-altitude conditions. This feature helps to maintain consistent engine performance and power output.

The carburetor features four 1.75-inch venturi throats, which are the areas where the fuel and air mixture is formed before being delivered to the engine. The venturis are equipped with circular, flat-top floats that are adjustable for fine-tuning the fuel mixture. The float level can be adjusted by removing the float bowls and using a float level gauge to set the correct level.

The Zenith 15320 VG4D Wisconsin Carburetor also includes a number of other adjustments to help optimize engine performance. These include the idle mixture screws, which can be adjusted to set the ideal idle fuel mixture, and the main jet and power jet, which can be adjusted to set the fuel mixture for various engine speeds and load conditions.

The carburetor body is made of high-quality aluminum alloy, which is both lightweight and durable. The main jets and power jets are made of stainless steel, which provides excellent resistance to corrosion and wear. The fuel bowl gaskets are made of Viton, a high-performance elastomer material that provides excellent sealing and resistance to fuel and oil.

The Zenith 15320 VG4D Wisconsin Carburetor comes with a number of accessories to make installation and tuning easier. These include fuel bowls with float bowls, needle jets, and float bowls, as well as a set of adjustment tools. The carburetor also includes a manual that provides detailed instructions on installation, tuning, and maintenance.
