The Honda 16100-Z3S-802 Carburetor Assembly (BE89M B) is a genuine OEM carburetor built for GX440 horizontal shaft engines. As a direct Honda OEM component, this carburetor is manufactured to the exact specifications of the original unit it replaces, ensuring correct jetting, fuel metering, and air-fuel mixture delivery right out of the box. The BE89M B variant designation identifies this specific calibration — confirm your existing carburetor carries a matching designation before ordering to ensure this is the correct unit for your engine.
Key Features
- Correct Jetting and Fuel Metering — as a genuine Honda OEM carburetor, this assembly is calibrated to the precise fuel delivery specifications the GX440 engine requires, not a generic approximation
- Variant-Specific Fitment — the BE89M B designation identifies a distinct carburetor calibration; match this code to the original unit on your engine before installing
- Fits GX440 Horizontal Shaft Engines — designed specifically for the GX440 platform; verify your engine's serial number against the fitment table, as Honda supersedes carburetor part numbers at serial breaks
- Restored Engine Performance — a worn or failing carburetor causes hard starting, rough idle, and poor throttle response; replacing it with this OEM assembly restores smooth fuel delivery and consistent power output
The carburetor is responsible for blending air and fuel in the correct ratio before delivering the mixture to the engine's combustion chamber. On a GX440 horizontal shaft engine, a properly functioning carburetor ensures clean starting, stable idle, and responsive power across the full throttle range. When a carburetor wears out, becomes clogged, or develops internal faults, the engine typically exhibits symptoms such as hard starting, hunting at idle, hesitation under load, or an inability to reach full power — replacing the assembly with a correctly specified OEM unit is the most reliable path to restoring normal operation.
