The Wacker Neuson Main Jet is a genuine OEM component designed for BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series machines. As a direct OEM replacement, this main jet is manufactured to the exact specifications Wacker Neuson requires to keep fuel delivery precise and combustion consistent. Sourcing the correct OEM part means no guesswork on fitment — cross-references directly to the carburetor assemblies used across the BPS and A5000 pump lines. If your machine is running rough, flooding, or starving for fuel, replacing a worn or clogged main jet with this genuine part is the right first step.
Key Features
- Exact OEM Fuel Metering Spec — Manufactured to Wacker Neuson's precise orifice dimensions, ensuring the correct air-to-fuel ratio is delivered to the carburetor at all throttle positions.
- Drop-In Carburetor Fitment — Threads directly into the carburetor body on compatible models with no reworking or adapting of the fuel circuit required.
- Broad BPS and A5000 Series Coverage — Confirmed fit across BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B models, covering a wide range of Wacker Neuson pump applications.
- Restored Engine Response — A correctly sized main jet keeps the engine pulling cleanly under load; a worn or partially blocked jet causes rough running, power loss, and hard starting.
- Fuel System Integrity — Using a genuine OEM jet with the correct flow rating helps prevent over-rich or over-lean conditions that can damage pistons, valves, and other internal engine components over time.
The main jet is a small but critical component inside the carburetor that meters the volume of fuel mixed with incoming air during normal engine operation. Its precisely drilled orifice controls fuel flow at mid to full throttle, directly affecting power output, fuel efficiency, and exhaust emissions. When a main jet becomes clogged with varnish deposits, worn from extended use, or damaged, the engine will typically exhibit symptoms such as lean stumbling under load, black smoke from over-fueling, or a complete inability to reach full operating speed.
