The Honda 16100-Z9M-811 Carburetor Assembly (BB76G A) is a genuine OEM carburetor built for GCV170 and GCV200 vertical shaft engines and the HRX217 lawn mower. As a factory-original component, this carburetor assembly is manufactured to Honda's exact calibration — correct jet sizing, needle position, and fuel metering circuits are set from the factory, so the engine restores to its original starting behavior and throttle response the moment this part is installed. Confirm your machine's serial number against the fitment table before ordering, as Honda supersedes carburetor assemblies at specific serial breaks within these model lines.
Key Features
- Exact OEM Fuel Calibration — jets, emulsion circuits, and float settings match Honda's original specification for the BB76G A carburetor variant, restoring the precise air-fuel ratio GCV170 and GCV200 engines depend on for clean starting and smooth power delivery
- Direct-Fit Replacement — engineered as a drop-in assembly for the GCV170, GCV200, and HRX217, with matching bolt pattern, fuel inlet, and linkage geometry so installation follows Honda's standard service procedure
- Variant Identification Matters — the BB76G A designation identifies a specific carburetor configuration; verify this variant code matches what is stamped on your original carburetor before installing
- Serial Number Verification Recommended — Honda revises carburetor assemblies at production serial breaks, so cross-check your engine's serial number against the compatibility table to confirm part number 16100-Z9M-811 is correct for your unit
- Restored Engine Performance — a worn or gummed carburetor causes hard starting, rough idle, surging, and lean running; replacing it with this genuine assembly returns the engine to consistent, full-throttle output
The carburetor is the component responsible for blending air and fuel in the precise ratio the engine needs to run efficiently across its full operating range — from cold start through wide-open throttle. On GCV170 and GCV200 vertical shaft engines, including those fitted to the HRX217 lawn mower, the carburetor meters fuel through calibrated jets and a float-controlled bowl, responding to throttle input to regulate power output. When the carburetor wears, clogs with varnish deposits from stale fuel, or develops float or needle faults, the engine exhibits hard starting, rough idle, surging, or an inability to maintain full power — symptoms that a correct replacement carburetor assembly directly resolves.
