The Honda 16044-Z8T-W01 Choke Set is a genuine OEM replacement designed for GX240, GX270, GX340, and GX390 horizontal shaft engines, as well as EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500 generators. As an authentic Honda part, this Choke Set is sourced directly from Honda and built to the same standards as the original component it replaces. Verify your machine's serial number against the fitment table before ordering, as Honda supersedes parts at production breaks and more than one variant may exist across this model range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the choke set matches the original carburetor geometry and cold-start fuel enrichment calibration exactly.
- Cold-Start Fuel Metering — a correctly functioning choke set restricts airflow during startup to deliver the rich mixture these engines need to fire reliably from cold, particularly in demanding generator and commercial engine applications.
- Broad Compatibility — fits GX240, GX270, GX340, and GX390 horizontal shaft engines and EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500 generators, including models where the carburetor design is shared across the engine and generator platforms.
- Serial Number Verification Recommended — Honda updates parts at serial breaks within the same model family; always confirm your unit's serial number against the fitment table to ensure you receive the correct set for your machine.
The choke set is the assembly within the carburetor that controls airflow enrichment during cold starting. When the engine is cold, the choke plate closes across the carburetor throat, lowering air pressure in the venturi and drawing a richer fuel-air mixture into the cylinder — giving the engine the extra fuel it needs to ignite and run before it reaches operating temperature. Once the engine warms up, the choke opens fully to restore normal airflow and efficient combustion. A worn, damaged, or sticking choke set causes hard cold starts, rough idling, and poor fuel efficiency, and on generator applications it can prevent the engine from reaching the stable speed needed for clean power output. Replacing this component with a genuine Honda Choke Set restores proper cold-start behavior and smooth throttle response.
