The Wacker Neuson Carburetor is a genuine OEM component designed for BS50-2 and BS50-2i series vibratory rammers. As a direct OEM replacement, this carburetor is engineered to the same specifications as the original part, ensuring the fuel-air mixture your rammer depends on is delivered correctly every time. It is compatible across the full BS50-2 and BS50-2i range, covering standard and oil-injected variants in multiple shoe configurations including 165mm, 195mm, 250mm, 255mm, and 280mm shoe sizes. Verify your machine's model number against the fitment list to confirm compatibility before ordering.

Key Features

  • OEM Fuel-Air Calibration: — Built to the exact metering and jetting specifications of the original carburetor, so your rammer starts reliably and runs at the correct fuel-air ratio under load.
  • Drop-In Fitment for BS50-2 and BS50-2i: — Mounts directly to the engine using the original hardware and connection points, covering both standard and oil-injected BS50-2 configurations.
  • Wide Shoe Size Coverage: — Fits BS50-2 and BS50-2i rammers across 165mm, 195mm, 250mm, 255mm, and 280mm shoe configurations, including EU variants.
  • Consistent Engine Response: — A properly functioning carburetor maintains steady throttle response and full compaction force stroke; a worn or clogged unit causes hard starting, rough running, and loss of output power.
  • Fuel System Integrity: — Genuine OEM construction ensures all internal passages, needle seats, and float components meet the original design tolerances, reducing the risk of fuel delivery faults or uncontrolled engine behavior.

The carburetor is responsible for mixing fuel and air in the correct ratio before delivering that mixture to the engine's combustion chamber. On a vibratory rammer like the BS50-2 series, precise fuel metering is critical — too lean a mixture causes overheating and power loss, while too rich a mixture leads to fouled plugs, excessive fuel consumption, and rough operation. When a carburetor wears out or becomes blocked, symptoms typically include difficulty starting, inconsistent throttle response, and reduced compaction performance. Replacing it with a correctly specified OEM unit restores the engine's original operating characteristics.
