The Honda 16100-ZJ4-V12 Carburetor Assembly (BG23D B) is a genuine OEM Carburetor Assembly designed for GXV610 and GXV620 vertical shaft engines. As a factory-sourced component, this carburetor is built to Honda's original specifications, ensuring the correct jetting, fuel metering, and air-fuel mixture delivery for these engines. Verify your engine's serial number against the fitment table before ordering — Honda supersedes carburetor assemblies at serial number breaks, and the BG23D B variant designation identifies this as a specific calibration within the GXV610 and GXV620 range.
Key Features
- OEM Fuel Metering Accuracy — engineered to Honda's original jetting specifications, this carburetor delivers the correct air-fuel ratio for consistent starting and smooth throttle response on GXV610 and GXV620 engines.
- Variant-Specific Calibration — the BG23D B designation identifies a precise carburetor specification; confirm this variant matches your engine's serial number range before installation.
- Direct OEM Replacement — sourced directly from Honda, this assembly replaces the original unit without modification, using the same mounting configuration and fuel circuit layout as the part it replaces.
- Serial Number Awareness — Honda updates carburetor specifications at production serial breaks; check your GXV610 or GXV620 serial number against the compatibility table to confirm this is the right assembly for your engine.
A carburetor is responsible for mixing fuel and air in the precise ratio an engine needs to run efficiently. On GXV610 and GXV620 vertical shaft engines, the carburetor assembly meters fuel from the tank, combines it with filtered air, and delivers the mixture to the combustion chamber at the correct volume for the load and throttle position. When a carburetor wears, clogs, or develops internal leaks, the engine may run rough, idle poorly, surge under load, or fail to start altogether. Replacing a failed or deteriorated carburetor with a correct OEM unit restores proper fuel delivery and returns the engine to its designed operating condition.
