The Honda 16100-Z9H-802 is a genuine OEM Carburetor Assembly (BE80W A/B) designed for GX340 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly is manufactured to the same specifications as the original unit, ensuring correct jetting, fuel metering, and air-fuel mixture delivery right out of the box. Honda supersedes carburetor assemblies at serial breaks, so confirm your GX340 serial number against the fitment table before ordering to make sure part number 16100-Z9H-802 is the right match for your engine build.
Key Features
- Correct Fuel Metering — genuine OEM construction means the jets, needle, and emulsion circuits are calibrated exactly as Honda specifies for the GX340, delivering the proper air-fuel ratio under load
- Direct OEM Replacement — this carburetor assembly replaces the original unit with no re-jetting or adaptation needed; all mounting flanges and fuel inlet connections match the GX340 engine's existing configuration
- BE80W A/B Variant — the (BE80W A/B) designation identifies this as a specific carburetor variant; confirm this code matches the original unit on your engine before purchasing
- Serial Number Awareness — Honda updates carburetor assemblies at production serial breaks; check your GX340 serial number against the fitment table to confirm this is the correct supersession for your engine
- Restored Engine Performance — a worn or dirty carburetor causes hard starting, rough idle, fuel flooding, and loss of power under load; replacing it with this genuine assembly returns the engine to clean, consistent combustion
The carburetor is responsible for mixing fuel and air in the precise ratio the engine needs to start, idle, and run under varying loads. On a GX340 horizontal shaft engine, it draws fuel from the tank, meters it through calibrated jets and a needle circuit, and blends it with filtered air before delivering the mixture to the combustion chamber. When the carburetor wears, clogs, or develops internal leaks, the engine struggles to start, runs unevenly, surges at governed speed, or floods — problems that a fresh OEM assembly corrects directly at the source.
