Wacker Neuson 5200007836 Carburetor Adjustment Plug

The Wacker Neuson is a genuine OEM Carburetor Adjustment Plug designed for the BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS65-V, MS52, and MS62 series vibratory rammers. As a direct-from-manufacturer component, part is produced to the same specifications as the original plug fitted at the factory, ensuring a correct, interference-free installation in the carburetor adjustment port. This part covers an extensive range of BS-series rammer configurations — including standard, oil-injected, variable-speed, high-altitude, and EU variants — so confirming your model number against the fitment list before ordering is always recommended. When the adjustment plug is damaged, missing, or improperly seated, the carburetor's mixture circuit is exposed to contamination and the fuel-air calibration can drift, leading to hard starting, erratic running, or excessive fuel consumption.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's original material and dimensional specification, maintaining the airtight seal critical to a correctly calibrated carburetor adjustment port.
• Direct-Fit Replacement — Seats directly into the carburetor adjustment port on covered BS-series rammers with no machining or modification to the carburetor body.
• Broad BS-Series Coverage — Verified fitment across BS50-2, BS50-2i, BS60-2, BS60-2i, BS70-2, BS70-2i, BS65-V, MS52, and MS62 rammer families, including standard, oil-injected, high-altitude, EU, and BG Bau-approved variants.
• Protects Mixture Calibration — Keeps the fuel-air adjustment circuit sealed against debris and moisture ingress, preserving the tuned mixture setting that governs clean starting and consistent impact energy.
• Fuel System Safety — A correctly installed adjustment plug prevents uncontrolled access to the mixture circuit, reducing the risk of inadvertent adjustment or contamination that could create unsafe running conditions in the field.

The carburetor adjustment plug seals the mixture-adjustment port on a two-stroke carburetor, locking in the factory-set or tuned fuel-air ratio and blocking dirt, water, and debris from entering the metering circuit. On vibratory rammers operating in dusty or muddy trench conditions, this small plug plays an outsized role — without it, fine particles can migrate into the needle or jet passages, altering the mixture and causing poor throttle response, fouled plugs, or stalling under load. Replacing a worn, cracked, or missing plug restores the integrity of the carburetor's sealed circuit and returns the rammer to stable, consistent performance.
