The Honda 16100-Z8B-901 is a genuine OEM Carburetor Assembly (BB76A A) designed for GCV160 vertical shaft engines, HRR216 lawn mowers, and HRS216 lawn mowers. As a direct Honda OEM component, this carburetor is built to the same specification as the unit it replaces, ensuring the correct jetting, needle position, and fuel metering circuits Honda engineered into these machines from the factory. Confirm your engine's serial number against the fitment table before ordering, as Honda supersedes carburetor assemblies at specific serial breaks. This assembly is the BB76A A variant — verify that designation matches your existing carburetor before purchasing.
Key Features
- Correct Jetting and Fuel Metering — as a genuine Honda OEM carburetor, this assembly carries the exact main jet sizing, pilot circuit, and emulsion tube configuration specified for the BB76A A application, so air-fuel ratio is right from the first start
- Direct OEM Replacement — engineered to mount and connect exactly as the original, with matched throttle bore dimensions and inlet fitting geometry for the GCV160 engine
- Broad Fitment Coverage — covers GCV160 vertical shaft engines as well as HRR216 and HRS216 lawn mowers; confirm your model and serial number against the compatibility table to select the correct assembly
- Restores Clean Running — a worn or gummed carburetor causes hard starting, rough idle, surging, and loss of power; replacing it with this OEM assembly brings fuel delivery back to specification
The carburetor is the component responsible for mixing air and fuel in the precise ratio the engine needs to run efficiently across the full throttle range. It meters fuel through calibrated jets and passages, responding to throttle input to deliver the right mixture at idle, mid-range, and full load. When a carburetor degrades — whether from varnish buildup, worn needle seats, or corroded passages — the engine struggles to start, surges at steady throttle, or runs rich and fouls the spark plug. Replacing the assembly with a genuine Honda unit restores proper fuel metering and returns the engine to smooth, responsive operation.
