The Honda 16100-Z0J-013 Carburetor Assembly (BB61J B) is a genuine OEM component designed for GC135 and GC160 horizontal shaft engines, EN2000 and EN2500 generators, FG400 and FG500 tillers, and WN20 and WN30 water pumps. As a direct Honda OEM part, this carburetor assembly is built to the same specification as the unit installed at the factory, ensuring correct fuel metering, air-fuel mixture, and throttle response across every application it covers. Confirm your machine's model and serial number against the fitment table before ordering, as Honda supersedes carburetors at production breaks and the BB61J B variant designation identifies this specific calibration.
Key Features
- Correct Jetting and Fuel Calibration — as a genuine Honda OEM carburetor assembly, part number 16100-Z0J-013 carries the BB61J B circuit calibration engineered for the fuel delivery demands of its covered engines and equipment, not a generic approximation.
- Broad Cross-Equipment Fitment — covers GC135 and GC160 horizontal shaft engines, EN2000 and EN2500 generators, FG400 and FG500 tillers, and WN20 and WN30 water pumps, including a wide range of serial ranges across each platform.
- Verify the BB61J B Variant — multiple carburetor assemblies are listed across these models; match the BB61J B designation to the part currently on your machine before installing to confirm this is the correct unit for your specific serial range.
- Restored Throttle Response and Starting — a carburetor that is worn, gummed, or incorrectly calibrated causes hard starting, rough idle, and loss of power under load; replacing it with this assembly returns the engine to clean, responsive operation.
The carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to start cleanly and run efficiently under varying loads. It meters fuel through calibrated jets and passages, responding to throttle position and engine demand to maintain smooth combustion. When a carburetor becomes clogged with varnish deposits, develops worn needle seats, or suffers damaged diaphragms or float components, the engine will struggle to start, idle erratically, surge under load, or run rich and foul the spark plug — replacing the assembly with a correctly specified unit like this one restores clean fuel delivery and dependable performance across generators, tillers, water pumps, and the horizontal shaft engines that power them.
