The Honda 16100-Z5T-741 is a genuine OEM Carburetor Assembly (BE89R A) designed for GX390 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly is engineered to Honda's own specifications, ensuring correct jetting, fuel metering, and air-fuel mixture calibration right out of the box. Honda supersedes carburetors at serial number breaks, so confirm your engine's serial number against the fitment table before ordering to ensure part number 16100-Z5T-741 is the correct assembly for your unit.
Key Features
- Correct Jetting and Fuel Metering — as a genuine OEM assembly, this carburetor carries Honda-specified jet sizing and needle settings, so the GX390 engine delivers the air-fuel ratio it was designed to run on from the first start.
- Variant-Specific Calibration — the BE89R A designation identifies a specific carburetor calibration; match this code to your original unit to ensure you are installing the correct assembly for your application.
- Direct OEM Replacement — this assembly installs in place of the original carburetor with no rework, using the same mounting interface and fuel line connections as the part it replaces on GX390 engines.
- Serial Number Verification Recommended — Honda updates carburetor assemblies at production breaks, so check your engine's serial number against the compatibility table to confirm this is the right assembly for your GX390.
A carburetor blends fuel and air in the precise ratio an engine needs to run cleanly under load. On the GX390 horizontal shaft engine, the carburetor assembly draws fuel from the tank, meters it through calibrated jets and a needle valve, and delivers a combustible mixture to the cylinder. When a carburetor wears or becomes fouled, the engine may run rough, hesitate under load, run rich or lean, or refuse to start. Replacing the assembly with a correct OEM unit restores the fuel delivery the engine was built around and brings performance back to specification.
