The Honda 16100-Z9H-WA1 is a genuine OEM Carburetor Assembly (BEA5C B) designed for GX340 horizontal shaft engines. As a direct Honda OEM component, this carburetor assembly is built to the exact specifications required for proper fuel metering and engine performance on GX340 applications. The BEA5C B designation identifies this as a specific carburetor variant — confirm part number 16100-Z9H-WA1 against your engine's serial number and existing carburetor before ordering to ensure you have the correct unit for your machine.
Key Features
- Correct Jetting and Fuel Metering — as a genuine Honda OEM part, this carburetor assembly carries the precise jetting, needle settings, and main jet calibration matched to GX340 engine specifications, restoring the air-fuel ratio the engine was designed to run on.
- Variant-Specific Fitment — the BEA5C B designation identifies a specific carburetor configuration within the GX340 lineup; match this variant to your existing unit before installation to confirm compatibility with your engine build.
- GX340 Horizontal Shaft Engine Application — engineered for GX340 horizontal shaft engines; check your engine's serial number against the fitment table to confirm this assembly covers your serial range.
- Restored Engine Starting and Power Delivery — a worn or clogged carburetor causes hard starting, rough idle, and power loss; replacing it with this OEM assembly brings fuel delivery back to spec and restores consistent engine output.
The carburetor is the heart of the engine's fuel system, responsible for mixing air and fuel in the precise ratio the engine needs to start reliably, idle smoothly, and deliver full power under load. On GX340 horizontal shaft engines, a carburetor that is worn, clogged, or damaged will typically present as difficulty starting, erratic idling, fuel flooding, or a noticeable drop in power output. Replacing the carburetor assembly with the correct OEM unit returns fuel metering to the engine's original specification and eliminates the performance issues a degraded carburetor introduces.
