Review ZENITH Clark Carburetor

The Zenith 671409 carburetor, also known as the Clark CHF-77B or the 10536A, is a high-performance, four-barrel carburetor designed for use in aircraft engines. This carburetor is a direct replacement for the older model 6-71 series carburetors and offers several upgrades for improved engine performance and fuel efficiency.

The 671409 carburetor features four 2.16-inch venturi throats, each with its own individual float bowl. This design provides a more consistent fuel mixture and better idle quality compared to traditional two-barrel or single-carburetor setups. Each venturi throat is equipped with a 32-pitch mechanical secondary metering rod, which allows for precise fuel metering and delivery to the engine.

One of the key upgrades of the Zenith 671409 carburetor is its electric choke system. This feature eliminates the need for a manual choke and makes starting the engine easier and more consistent, especially in cold weather conditions. The electric choke system is controlled by a switch on the cockpit panel and engages automatically when the throttle is advanced during startup.

Another upgrade is the use of a high-performance air filter. The air filter is designed to provide excellent filtration while also allowing for easy access for cleaning or replacement. The filter is located at the top of the carburetor, making it easy to remove and inspect.

The 671409 carburetor also features a built-in fuel pressure regulator, which maintains a consistent fuel pressure at the carburetor inlet. This helps ensure that the engine receives an optimal fuel mixture, regardless of altitude or engine RPM. The fuel pressure regulator is adjustable, allowing for fine-tuning of the fuel mixture to optimize engine performance.

The carburetor is constructed of high-quality materials, including billet aluminum and stainless steel components. The aluminum body is anodized for durability and corrosion resistance, while the stainless steel floats and needle valves provide excellent wear resistance and long service life.

The Zenith 671409 carburetor is easy to install and comes with all necessary hardware, including mounting brackets, fuel lines, and electrical connectors. The carburetor is also compatible with a wide range of aircraft engines, making it a versatile and practical choice for many applications.

Overall, the Zenith 671409 carburetor is a high-performance, reliable, and easy-to-install carburetor for aircraft engines. Its upgrades, such as the electric choke system, high-performance air filter, and built-in fuel pressure regulator, make it a superior choice for pilots who demand the best from their aircraft.
