The Wacker Neuson is a genuine OEM Float Set designed for the RD12A-90 tandem roller series, RD11A and RD11AEC hydrostatic double drum vibratory rollers, the BFS 2020AS floor saw, and the GS12Ai portable generator. Sourced directly from Wacker Neuson, this Float Set matches the exact specifications of the original component installed at the factory. Whether you are servicing a walk-behind tandem roller on an asphalt crew or keeping a floor saw or generator running on site, part number ensures a direct, compatible replacement. Cross-referencing your machine's serial number against the fitment list above is always recommended before ordering.
Key Features
- Genuine OEM Construction: — Manufactured to Wacker Neuson's original material and dimensional tolerances, ensuring the float maintains correct fuel level regulation without drift or misalignment over time.
- Broad Multi-Machine Compatibility: — Fits the RD12A-90 tandem roller (including Foldable ROPS variant), RD11A and RD11AEC hydrostatic double drum rollers, BFS 2020AS floor saw, and GS12Ai 50Hz portable generator.
- Drop-In Carburetor Fit: — Designed to seat correctly within the original carburetor float chamber, requiring no trimming or modification to achieve proper float height and fuel shutoff function.
- Stable Fuel Metering Across Demanding Conditions: — A correctly functioning float set holds fuel delivery steady during continuous operation; a worn or saturated float causes flooding, rough running, or hard starting.
- Fuel System Integrity: — Maintaining a properly sealed and buoyant float prevents uncontrolled fuel flow, which is critical for safe, consistent engine operation across all compatible machines.
A float set is the buoyancy-controlled valve mechanism inside a carburetor's fuel bowl. As the fuel level in the bowl rises, the float lifts and presses a needle valve closed, cutting off incoming fuel; as the engine consumes fuel and the level drops, the float descends and allows the valve to reopen. This continuous cycle keeps the fuel-air mixture within the narrow range the engine needs to run cleanly and efficiently. When a float becomes saturated, cracked, or damaged, it loses buoyancy, causing the bowl to overfill and flood the engine — resulting in fuel-rich running, excessive smoke, poor power output, or a complete no-start condition.
