Notched Float w/Jet Ext.

The Holley Notched Float with Jet Extension (part number 116-10) is a precision carburetor component designed for builders and enthusiasts who require reliable fuel management in various engine builds and operating conditions. This notched float design works with Holley's jet extension system to ensure consistent fuel delivery, making it a vital upgrade or replacement for custom carburetors and high-performance engines.

The notched design aims to reduce fuel slosh and improve float stability during acceleration and cornering, which can help prevent fuel starvation. By integrating the jet extension, the float allows for precise adjustments of the fuel needle height without bending the float arm, enhancing repeatability for tuners during testing sessions. The lightweight construction is intended to minimize inertia lag, ensuring quick response to transient fuel demands.

This float assembly is compatible with Holley two and four-barrel models, making it suitable for various applications, including street, strip, and off-road engines. Proper float assembly geometry is crucial for optimizing cold-start behavior, idle quality, and wide-open-throttle response, benefiting those tuning classic muscle cars or modern restomods.
