Wacker Neuson 5000183841 Carburetor Walbro HDA291 11.1mm

The Wacker Neuson Carburetor Walbro HDA291 11.1mm is a genuine OEM component designed for the BS50-2, BS50-2i, BS60-2i, BS65-V, BS70-2, and BS70-2i series vibratory rammers. As a direct OEM part sourced through Wacker Neuson's authorized supply chain, the is built to the same specification as the unit installed at the factory — ensuring correct fuel metering, throttle response, and engine performance from the first pull. This carburetor fits an extensive range of BS-series rammers across standard, oil-injected, EU, and high-altitude configurations, making it one of the most widely applicable fuel system components in the Wacker Neuson rammer lineup. When your rammer's carburetor is worn, clogged, or damaged, replacing it with the correct OEM unit restores consistent starts and smooth power delivery across the full operating cycle.

Key Features

• Calibrated Fuel Delivery: — The Walbro HDA291 design meters fuel at the correct 11.1mm specification, maintaining the precise air-to-fuel ratio the BS-series two-cycle engine requires for consistent power output.
• Genuine OEM Part: — Sourced directly from Wacker Neuson, part number 5000183841 carries the same quality and dimensional tolerances as the original unit — no guesswork on fit or function.
• Direct-Mount Replacement: — Engineered as a drop-in unit for supported BS-series rammers; mounts to the existing intake and throttle linkage without modification to surrounding components.
• Broad BS-Series Compatibility: — Fits BS50-2, BS50-2i, BS50-2plus, BS60-2i, BS65-V, BS70-2, and BS70-2i rammers across multiple shoe sizes, regional specs, and high-altitude configurations.
• Fuel System Safety: — A properly seated OEM carburetor prevents unmetered fuel delivery and potential flooding conditions, reducing the risk of uncontrolled starts or fuel system hazards on active job sites.

The carburetor is the component responsible for mixing air and fuel in the correct ratio before that mixture enters the engine's combustion chamber. On a two-cycle vibratory rammer like the BS-series, the carburetor must deliver a consistent, precisely metered charge under varying throttle loads and operating conditions — including high-altitude environments where air density changes. When a carburetor wears out or becomes restricted by varnish and debris, the engine may run rough, fail to start, surge under load, or stall during compaction work. Replacing the carburetor with the correct OEM unit — in this case the Walbro HDA291 at 11.1mm — restores proper fuel delivery and brings the engine back to its specified operating condition.
