The Honda 16100-Z4X-V21 is a genuine OEM Carburetor Assembly (BE54B A) designed for GX160 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly is manufactured to the same specification as the part that left the factory, ensuring correct jetting, needle position, and fuel metering for the GX160. Honda supersedes carburetor assemblies at serial number breaks, so confirm your engine's serial number against the fitment table before ordering to ensure part number 16100-Z4X-V21 is the correct variant for your unit. The BE54B A designation identifies this as a specific carburetor variant — match it carefully if your engine has been updated or previously serviced.
Key Features
- Correct Jetting and Fuel Metering — genuine Honda OEM construction means the main jet sizing, pilot circuit, and needle clip position are calibrated specifically for the GX160, so the engine runs at the fuel-air ratio Honda engineered it for.
- Variant-Specific Fit — the BE54B A designation identifies a specific carburetor configuration; using part number 16100-Z4X-V21 ensures you receive the exact assembly your engine requires rather than a mismatched variant.
- Serial Number Matters — Honda releases updated carburetor assemblies mid-production, so always verify your GX160 serial number against the compatibility table to confirm this is the right assembly for your engine.
- Restored Starting and Running Performance — a worn or degraded carburetor causes hard starting, rough idling, and loss of power under load; replacing it with this OEM assembly restores clean throttle response and steady operation.
The carburetor is responsible for mixing fuel and air in the correct ratio before delivering the mixture to the engine's combustion chamber. On the GX160, it meters fuel through precision-calibrated jets and passages at idle, mid-throttle, and wide-open throttle positions. When the carburetor wears, gums up from stale fuel, or its internal passages become blocked, the engine will struggle to start, run unevenly, surge at idle, or lose power under load — symptoms that a replacement carburetor assembly directly resolves.
