The Wacker Neuson Main Jet is a genuine OEM main jet designed for BPS1550B, BPS2050B, and A5000/160B series equipment. As a direct OEM part, it is manufactured to the exact specification of the original component, ensuring correct fuel metering and consistent engine performance across all compatible models. This includes both standard and water-cooled BPS1550Bw and BPS2050Bw variants. If your machine is running lean, flooding, or struggling to hold a steady throttle, replacing the main jet with the correct Wacker Neuson is the reliable path back to proper operation.
Key Features
- Calibrated Fuel Metering Orifice — Manufactured to the precise bore diameter required for correct air-fuel ratio across the full RPM range of compatible Wacker Neuson engines.
- Drop-In Carburetor Fit — Threads directly into the carburetor body float bowl seat, matching the original fitment with no rework or adaptation to the fuel system.
- Broad Model Coverage — Fits BPS1550B, BPS1550Bw, BPS2050B, BPS2050Bw, and A5000/160B series, covering both standard and water-cooled pump configurations.
- Protects Engine Efficiency — A correctly sized main jet keeps combustion clean and fuel consumption in check; a worn or partially blocked jet causes rough running, power loss, and potential engine damage over time.
- Fuel System Integrity — As an OEM component in a metered fuel circuit, using the correctly specified jet prevents over-rich or over-lean conditions that can damage pistons, valves, and exhaust components.
The main jet is a small, precision-machined orifice fitted inside the carburetor that controls how much fuel is drawn into the engine under normal running load. Its bore size is calibrated specifically for the engine's displacement and airflow characteristics, so even a minor deviation in size — from wear, blockage, or an incorrect replacement — directly affects how the engine runs. A clogged or damaged main jet typically causes hesitation, stalling, or a significant loss of power under load, making it one of the first components to inspect during carburetor service.
