Center Hung Brass Float

The Holley Center Hung Brass Float (part number 116-2) is a precision carburetor component engineered for primary circuit operation in Holley carburetors. This center-hung brass float manages fuel level in the main bowl, directly affecting fuel delivery consistency and engine tuning stability. The brass construction provides reliable float integrity across temperature cycles common in high-performance and street-driven applications, where carburetor tuning precision translates directly to throttle response and overall drivability.

Holley center-hung float designs suspend the fuel-sensing mechanism from a central pivot point, reducing sensitivity to vehicle attitude changes during acceleration, braking, and cornering. Brass floats resist corrosion from ethanol-blended fuels and maintain dimensional stability better than some alternative materials, ensuring consistent float closure and needle valve seating. At 0.07 lbs, this component weighs little but carries significant responsibility—improper float function causes lean or rich stumble, hesitation, and carb flooding. The compact 4.95 x 1.75 x 6.95-inch profile fits within Holley's established mounting envelope, making replacement straightforward for rebuilds or upgrades.

This float suits carburetor rebuilders, engine builders, and enthusiasts performing Holley carb maintenance or restoration. Whether rebuilding a street engine, refreshing a classic-car fuel system, or diagnosing tuning issues, a worn or damaged float is often the culprit behind inconsistent idle quality or fuel overflow. Sourcing an OEM Holley replacement ensures dimensional accuracy and compatibility with the carburetor's internal geometry.

Holley carburetors remain popular in hot-rod, street-rod, and classic-car communities because of their robust design and wide availability of replacement parts. The center-hung float configuration is standard across many Holley models, making this component a common maintenance item for anyone running a Holley four-barrel or two-barrel carb. Verifying compatibility with your specific carburetor model before ordering ensures proper fitment.
