The Wacker Neuson Carburetor Float Set is a genuine OEM component designed for a wide range of Wacker Neuson equipment, including the PT3 trash pump series, BFS and BFSX floor saw series, BPU 3050 reversible vibratory plate, and GPi4300 and GPSi4300 portable inverter generators. As a direct OEM part, the is manufactured to the exact tolerances and material specifications required for proper carburetor fuel metering across all compatible models. Sourcing the genuine Wacker Neuson part ensures the float matches the carburetor bowl geometry and needle valve interface — no guesswork, no fitment adjustments. Keep a spare on hand for planned maintenance or unscheduled repairs across your fleet.
Key Features
- OEM-Matched Float Buoyancy: — Manufactured to the precise density and dimensions required to maintain correct fuel level in the carburetor bowl, preventing over-fueling or fuel starvation.
- Drop-In Carburetor Compatibility: — Engineered to seat correctly against the needle valve and bowl in the original carburetor assembly, ensuring a clean installation without shimming or rework.
- Broad Fleet Coverage: — A single part number covers PT3 trash pumps, BFS and BFSX floor saws, BPU 3050 reversible plate compactors, and GPi4300 and GPSi4300 inverter generators — useful for mixed fleets.
- Fuel System Integrity: — A properly functioning float keeps the fuel level consistent, supporting smooth throttle response and stable engine speed under load. A degraded or cracked float causes flooding, hard starting, and rough running.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson's authorized parts supply, carrying the same part number 5000156631 used by dealers and service centers.
The carburetor float is a small buoyant component inside the carburetor bowl that regulates how much fuel enters the carburetor at any given time. As fuel fills the bowl, the float rises and pushes the needle valve closed, cutting off the fuel supply — much like a float valve in a tank. When fuel is consumed, the float drops and the valve opens again, maintaining a steady fuel level. If the float becomes saturated, cracked, or deformed, it can no longer regulate fuel correctly, leading to a flooded engine, fuel leaking from the carburetor, or an engine that won't start or runs erratically. Replacing a worn float restores accurate fuel metering and returns the engine to normal operation.
