The Wacker Neuson is a genuine OEM Idle Speed Screw designed for the BS50-4 and BS60-4 series four-stroke vibratory rammers. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory. Fitment covers a wide range of BS50-4 and BS60-4 model variants, including standard, EU-specification, and "s" suffix configurations. Keep part number on hand to restore precise idle control and get your rammer back to work fast.
Key Features
- Calibrated Idle Control: — Sets and holds the correct idle speed in the carburetor circuit, keeping the engine stable between compaction strokes.
- Genuine OEM Component: — Manufactured to Wacker Neuson's exact thread pitch and adjustment tolerances, ensuring consistent throttle response from the first turn.
- Broad BS-Series Fitment: — Compatible with BS50-4, BS50-4s, BS60-4, and BS60-4s vibratory rammers across standard and EU model variants.
- Direct Carburetor Replacement: — Installs into the existing carburetor idle circuit with no re-tapping or modification to the housing needed.
- Restores Smooth Low-Speed Operation: — A worn or missing idle screw causes erratic idling, stalling, or inability to maintain low RPM; replacing it brings the engine back to stable, controllable operation.
- Fuel System Precision: — Correct adjustment of the idle mixture is critical to safe, clean-running engine operation and helps prevent rich-running conditions that can foul the spark plug or flood the engine.
The idle speed screw is a small but critical component in the carburetor's low-speed fuel circuit. It meters the air-fuel mixture at idle, allowing the engine to run smoothly when the operator is not actively driving the rammer. When this screw is worn, damaged, or missing, the engine may idle too fast, stall repeatedly, or refuse to settle at a stable RPM — all of which interrupt workflow and can indicate improper fueling that stresses the engine over time. Replacing part 5000159171 with a genuine Wacker Neuson screw restores the correct adjustment range and helps the carburetor perform as intended across a full day of trench and cohesive soil compaction work.
