The Wacker Neuson is a genuine OEM Fuel Inlet Needle designed for BS50-4 and BS60-4 series four-stroke vibratory rammers. As a direct factory replacement, this part meets the original engineering specifications for the carburetor fuel metering system on these machines. Fitment covers a wide range of BS50-4, BS50-4s, BS60-4, and BS60-4s models, including EU-spec variants, making the correct choice across the full four-stroke rammer lineup. Verify your machine number against the confirmed fitment list before ordering to ensure an exact match.
Key Features
- Genuine OEM Fuel Metering Accuracy — Manufactured to original tolerances so the needle seats and meters fuel precisely, maintaining the correct air-fuel ratio the carburetor was designed to deliver.
- Direct Carburetor Drop-In — Engineered to install directly into the carburetor inlet seat of BS50-4 and BS60-4 series rammers without reworking or adapting the fuel circuit.
- Broad BS-Series Coverage — Confirmed fitment across BS50-4, BS50-4s, BS60-4, BS60-4s, and EU-spec variants, covering both standard and 280mm/11in shoe configurations.
- Consistent Engine Performance — A worn or damaged fuel inlet needle causes flooding, lean-running, or hard-starting. Replacing it with part 5000158656 restores stable idle and full-power compaction strokes.
- Fuel System Integrity — Correct needle seating prevents uncontrolled fuel flow into the carburetor bowl, which is critical for safe, consistent operation of gasoline-powered compaction equipment.
The fuel inlet needle controls the flow of fuel into the carburetor float bowl by seating against the inlet valve to stop flow when the correct fuel level is reached. When the needle is worn, grooved, or fails to seat properly, the carburetor can flood the engine with excess fuel or allow it to run lean, leading to hard starts, rough idling, and loss of compaction power. Replacing a faulty needle is a fundamental carburetor service step that restores accurate fuel delivery and keeps the rammer running at its designed output.
