The Honda 16100-ZH8-W41 is a genuine OEM Carburetor Assembly (BE66D B) designed for GX160 horizontal shaft engines and Honda WB20, WB30, WD20, WD30, WT20, and WT30 water pumps. As an authentic Honda OEM component, this carburetor is manufactured to the exact specifications required for proper fuel metering and air-fuel mixture delivery on these units. Because Honda supersedes carburetor part numbers at serial breaks, verify your engine or pump serial number against the fitment table before ordering to confirm part number 16100-ZH8-W41 is correct for your specific unit. The BE66D B variant designation identifies this as a specific carburetor configuration — match it to your existing unit when replacing.
Key Features
- Correct Jetting and Fuel Metering — built to Honda's exact air-fuel calibration for the BE66D B carburetor specification, ensuring proper combustion and throttle response on GX160 engines and the Honda water pump models listed.
- Genuine Honda OEM Part — sourced directly from Honda, this carburetor assembly carries the same part number and configuration as the unit it replaces, with no adaptation required to seat and connect correctly.
- Broad Fitment Across Honda Engines and Water Pumps — covers the GX160 horizontal shaft engine as well as WB20, WB30, WD20, WD30, WT20, and WT30 water pumps; use the fitment table to confirm your model is included.
- Serial Number Verification Matters — Honda updates carburetor part numbers at production serial breaks; always check your unit's serial number against the compatibility table to confirm this assembly is the right fit for your machine.
- Restores Full Engine Output — a worn or degraded carburetor causes hard starting, rough idling, fuel starvation, and loss of power; replacing it with this OEM assembly returns the engine or pump to its intended operating performance.
A carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to run efficiently at any throttle position. On GX160 engines and the Honda water pumps this assembly serves, the carburetor controls fuel draw at idle, mid-range, and wide-open throttle through calibrated jets and passages sized for that specific engine displacement and application. When a carburetor wears, clogs, or develops internal leaks, the result is hard starting, unstable idle, excessive fuel consumption, or a complete inability to run under load — symptoms that replacing this assembly with the correct OEM unit will resolve.
