The Honda 16100-Z4M-WB1 is a genuine OEM Carburetor Assembly (BE61V A) designed for GX160 horizontal shaft engines, WH15, WH20, WT20, and WT30 water pumps. As a direct Honda OEM component, this carburetor assembly carries the exact jetting, fuel metering calibration, and circuit geometry Honda specifies for these applications — no guesswork on mixture delivery or idle tuning. This assembly is identified by variant code BE61V A, so confirm that code matches your existing carburetor before ordering, particularly if your engine or pump has had a prior carburetor replacement.
Key Features
- Correct Fuel Metering — genuine OEM construction means the jets, needle, and emulsion circuits are calibrated to Honda's specification for the BE61V A variant, delivering the air-fuel ratio these engines and pumps need to run cleanly at rated load
- Variant-Specific Fit — the BE61V A designation identifies this as a specific carburetor variant; buyers should match this code to the unit being replaced, especially if the machine has been serviced previously
- Wide Fitment Coverage — suits GX160 horizontal shaft engines and WH15, WH20, WT20, and WT30 water pumps; verify your serial number against the fitment table, as Honda supersedes carburetor assemblies at production breaks
- Restored Throttle Response and Starting — a worn or damaged carburetor causes hard starting, rough idle, fuel flooding, and loss of power under load; replacing it with this assembly restores clean fuel delivery and dependable throttle response
The carburetor is the component responsible for mixing air and fuel in the correct ratio before that charge enters the engine's combustion chamber. On small engines like the GX160 and the engines powering the WH and WT water pump lines, the carburetor must meter fuel precisely across idle, mid-range, and full-throttle circuits to maintain consistent power output. When a carburetor wears, becomes clogged with varnish from stale fuel, or develops a float or needle fault, the engine will exhibit symptoms ranging from hard starting and rough running to flooding or an inability to hold a steady speed — all of which directly affect the output and reliability of the equipment it powers. Replacing a failed unit with the correct OEM assembly is the surest way to return the engine to the performance Honda originally engineered.
