Wacker Neuson 5100061744 Carburetor Walbro

The Wacker Neuson Carburetor Walbro is a genuine OEM carburetor designed for the BH55, BH65, BH40, BH55rw, BH55rw rs, and BS30 series petrol breakers. As a direct OEM replacement, this Walbro carburetor is manufactured to the same specification as the original unit fitted at the factory, ensuring the engine receives the correct air-fuel mixture for consistent, reliable starts and smooth power delivery. Compatible across a broad range of Wacker Neuson breaker configurations — including 27x80, 28x160, 32x160, and 25x108 tool variants — this carburetor covers one of the widest fitment ranges in the BH and BS breaker lineup. Using the correct OEM part keeps your breaker running at peak output and avoids the rough running, stalling, and hard-start issues that a worn or incorrect carburetor causes.

Key Features

• OEM-Calibrated Fuel Metering — Manufactured by Walbro to Wacker Neuson's original specification, delivering the precise air-fuel ratio these petrol breaker engines require for clean combustion and consistent throttle response.
• Drop-In Replacement Fit — Matches the original carburetor mounting points, fuel inlet, and throttle linkage geometry on supported BH and BS series breakers, so installation follows the same procedure as the factory unit.
• Broad BH and BS Series Coverage — Fits BH40, BH55, BH55rw, BH55rw rs, BH65, and BS30 petrol breakers across multiple tool size configurations, making it the go-to carburetor across the Wacker Neuson light breaker range.
• Fuel System Integrity — A correctly functioning carburetor is a critical fuel system component; using a genuine OEM unit eliminates the risk of fuel leaks or vapor lock caused by substandard diaphragm materials or imprecise needle seat dimensions.
• Restored Starting Performance — Replaces the root cause of hard starts, rough idling, and engine stalling that result from a worn or damaged carburetor diaphragm, needle, or seat.

The carburetor is responsible for mixing air and fuel in the correct ratio before delivering that mixture to the engine's combustion chamber. On small two-stroke and four-stroke petrol breakers like the Wacker Neuson BH and BS series, a Walbro diaphragm-type carburetor draws fuel from the tank and meters it precisely in response to throttle demand and engine speed. When the carburetor wears or its internal diaphragm hardens and cracks, the engine loses the ability to maintain a stable idle, struggles to start, or cuts out under load — all of which bring work to a halt and put additional strain on other engine components.
