Wacker Neuson 5100069852 Needle Valve

The Wacker Neuson Needle Valve is a genuine OEM needle valve designed for the BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS62-2, BS68-2, and BS70-2 series rammers. As a direct OEM part, it is manufactured to the same specification as the original component fitted at the factory, ensuring proper fuel metering and carburetor function across all compatible models. Correct fitment is confirmed across a wide range of BS-series rammer variants, including US, high-altitude, and Sunbelt-designated configurations. When you need a dependable, like-for-like replacement, part number is the correct choice.

Key Features

• OEM Fuel Metering Accuracy — Manufactured to the original specification, this needle valve delivers precise fuel flow control within the carburetor, maintaining the correct air-fuel ratio your rammer depends on.
• Direct Carburetor Drop-In — Engineered to seat and seal exactly as the original, this valve installs directly into the carburetor without modification or adaptation to fitment hardware.
• Broad BS-Series Compatibility — Fits BS50-2, BS50-2plus, BS60-2, BS60-2plus, BS62-2, BS68-2, and BS70-2 series rammers, including standard, US, high-altitude, CN, and Sunbelt model variants.
• Protects Engine from Fuel Flooding — A worn or leaking needle valve can cause carburetor flooding, hard starting, or erratic engine behavior; replacing it restores consistent, controlled fuel delivery.
• Fuel System Safety — A correctly seating needle valve prevents uncontrolled fuel flow into the carburetor bowl, reducing the risk of flooding and fuel-related hazards during operation.
• Genuine Wacker Neuson Part — Supplied as a genuine OEM component backed by Wacker Neuson's parts program, so you can be confident in part number accuracy and build quality.

The needle valve sits inside the carburetor and controls the flow of fuel into the float bowl, opening and closing in response to the float position to maintain the correct fuel level at all times. When it functions correctly, the engine receives a consistent, metered fuel supply that supports smooth starting and steady power output. A worn, corroded, or damaged needle valve can stick open — causing flooding and fouled plugs — or stick closed, starving the engine of fuel entirely and preventing the machine from running.
