The Honda 16100-Z5T-801 Carburetor Assembly (BE85Z A) is a genuine OEM replacement built for GX390 horizontal shaft engines. Honda sources this assembly to the same specifications as the original unit, ensuring the correct jetting, needle setting, and fuel metering calibration for the GX390. Because Honda supersedes carburetor part numbers at serial breaks, confirm your engine's serial number against the fitment table before ordering to make sure part number 16100-Z5T-801 is the right match for your unit.
Key Features
- Correct Fuel Calibration — genuine OEM construction means the jetting, emulsion circuits, and fuel metering are set to Honda's specifications for the GX390, not approximated from a generic carb
- Drop-In Replacement — the BE85Z A variant designation identifies the exact carburetor assembly this engine requires; matching it to your unit avoids the fitment issues that come from using the wrong variant
- GX390 Fitment — designed specifically for GX390 horizontal shaft engines across the production run covered by this part number
- Serial Number Matters — Honda introduces superseded part numbers at defined serial breaks on the GX390; check your engine's serial number against the fitment table to confirm this is the correct assembly for your build
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 GX390, a properly functioning carburetor assembly maintains smooth throttle response and stable power output across varying conditions. When a carburetor wears, clogs, or develops internal damage, the engine may run rich or lean, idle roughly, surge under load, or refuse to start — replacing it with the correct OEM assembly restores proper fuel delivery and engine performance.
