Notched Float w/Jet Ext.

The Holley Notched Float with Jet Extension (part number 116-10) is a precision carburetor float engineered for center-hung mounting in classic Holley carburetors used across marine and automotive applications. Constructed from nitrophyl material, this float delivers the fuel level regulation necessary for consistent engine performance in demanding saltwater and freshwater environments. The notched design paired with jet extensions allows for precise tuning of fuel metering, critical for maintaining optimal combustion across varying throttle positions and operating conditions.

The jet extension feature enables fine adjustments to fuel delivery without requiring complete carburetor recalibration. Nitrophyl construction resists corrosion from ethanol-blended fuels and prolonged exposure to salt spray, maintaining dimensional stability and sealing integrity over extended seasons. The notched profile is specifically designed to work within Holley's fuel bowl geometry, ensuring proper float travel and preventing fuel starvation or overflow conditions that would otherwise compromise throttle response and engine reliability.

This float assembly suits boaters, classic automotive enthusiasts, and marine engine rebuilds where original equipment specifications demand Holley carburetor components. Whether restoring a vintage inboard engine, tuning a high-performance small block, or replacing worn fuel regulation hardware in an existing system, the 116-10 provides a direct-fit solution backed by Holley's heritage in carburetor engineering. Each unit ships ready to install as a replacement or upgrade component.

Carburetor float selection impacts starting behavior, fuel economy, and engine stability. A properly functioning float prevents pooling in the combustion chamber and maintains consistent jetting response. The notched geometry and jet extensions in this design accommodate fuel pressure variations typical in marine engine applications where ambient temperature and altitude shift fuel vapor characteristics. Weighing just 0.08 lbs, this precision component integrates seamlessly into complete Holley carburetor systems.
