The Honda 16100-ZH7-831 Carburetor Assembly (BE12C B) is a genuine OEM carburetor designed for GX120 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly is built to the exact specifications of the original unit, ensuring the correct fuel metering, air-fuel ratio, and jetting for the GX120. Confirm your engine's serial number against the fitment table before ordering to verify this is the right variant for your unit.
Key Features
- Correct Fuel Metering — genuine Honda OEM construction means the jets, needle, and emulsion circuits are calibrated specifically for the GX120, delivering the air-fuel ratio the engine was designed to run on.
- BE12C B Variant — the (BE12C B) designation identifies this as a specific carburetor variant; verify your engine's serial number against the fitment table to confirm this is the correct assembly for your unit.
- Direct OEM Replacement — this carburetor assembly replaces the original unit on GX120 horizontal shaft engines with no adaptation required, using the same mounting interface and fuel line connections as the part it replaces.
- Restored Engine Performance — a worn or damaged carburetor causes hard starting, rough idle, and poor throttle response; replacing it with part number 16100-ZH7-831 restores clean fuel delivery and consistent power output.
The carburetor is responsible for mixing air and fuel in the precise ratio the engine needs to start, idle, and run under load. On the GX120 horizontal shaft engine, the carburetor assembly meters fuel from the tank, atomizes it with incoming air, and delivers the mixture to the combustion chamber. When the carburetor wears out or becomes clogged — often from stale fuel deposits — the engine may run rough, surge, refuse to start, or stall under load; replacing the assembly restores proper combustion and full power.
