The CPA258 Hy-Garde Carburetor Choke, manufactured by Holley, is a high-performance choking system designed to provide consistent and reliable starting for various applications, particularly in carbureted engines. This choke is a significant upgrade from traditional carburetor chokes due to its innovative design and advanced features.

The CPA258 also comes with a machined brass vacuum port, which ensures a leak-free connection and provides a solid foundation for the vacuum diaphragm.

Additionally, the CPA258 is compatible with various fuel systems, including those that use ethanol and methanol. Holley offers an optional fuel-alcohol kit to accommodate these applications. The choke is also compatible with both 1 and 1 inch carburetor flanges, making it a versatile option for various engine setups.

In summary, the CPA258 Hy-Garde Carburetor Choke by Holley is a high-quality, reliable, and advanced choke system designed for carbureted engines. Its vacuum secondary operation, hardened steel choke plate, Hy-Garde vacuum diaphragm, adjustable vacuum port, and compatibility with various fuel systems make it an excellent choice for performance enthusiasts seeking a consistent and efficient starting solution.
