The Wacker Neuson Carburetor Membrane Set is a genuine OEM component designed for the BH 22, BH 23, and BH 24 series gasoline breakers. As a direct OEM replacement, this set is manufactured to the same specifications as the original part, ensuring correct fit and function across the full range of compatible BH models including BH 22 RS, BH 23 RS, BH 24 Low Vib, and BH 24 Low Vib RS variants. Keeping the carburetor membrane in good condition is essential to maintaining consistent fuel delivery and reliable engine operation on your breaker. Verify your model number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Membrane Material — Manufactured to OEM specification, ensuring the correct diaphragm thickness, flexibility, and fuel resistance required for a gasoline breaker carburetor.
- Direct Drop-In Replacement — Engineered to seat correctly within the carburetor body of compatible BH series breakers, with no trimming or modification to the housing needed.
- Broad BH Series Compatibility — Fits BH 22, BH 22 RS, BH 23, BH 23 RS, BH 24, BH 24 Low Vib, and BH 24 Low Vib RS gasoline breaker models.
- Restores Fuel Metering Accuracy — A fresh membrane set returns the carburetor to proper fuel-to-air ratio control, eliminating hard starting, rough running, and power loss caused by a cracked or stiffened diaphragm.
- Fuel System Integrity — Correct membrane condition prevents unmetered fuel flow and potential flooding, which matters when operating a gasoline-powered demolition tool in confined or enclosed work areas.
The carburetor membrane set is the group of flexible diaphragms inside a small-engine carburetor that regulate fuel draw and metering in response to engine demand. On a gasoline breaker like the BH series, these membranes flex thousands of times per minute to pull fuel from the tank and deliver the correct mixture to the combustion chamber. Over time, heat, fuel exposure, and mechanical fatigue cause the membranes to stiffen, crack, or distort — leading to hard starts, erratic idling, loss of power under load, or an engine that won't run at all. Replacing the membrane set restores consistent fuel delivery and brings the carburetor back to proper working order.
