The Honda 16045-Z2E-013 Choke Arm is a genuine OEM replacement designed for GX440 horizontal shaft engines. Sourced directly from Honda, this part meets every dimension and tolerance the original design calls for, ensuring the choke mechanism operates exactly as intended. If your GX440 engine is running rich, failing to start in cold conditions, or the choke is sticking or moving loosely, replacing the Choke Arm is a straightforward fix that restores proper fuel-air control.
Key Features
- Genuine Honda OEM — manufactured to Honda's original design specifications, so the lever geometry and pivot engagement match the carburetor's choke shaft exactly as built.
- Correct Cold-Start Control — a properly functioning Choke Arm allows the choke plate to open and close fully, giving the engine the rich mixture it needs to start and the clean air it needs once warm.
- Direct Fitment for GX440 Engines — engineered specifically for GX440 horizontal shaft engines; verify your serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
- Small Part, Real Consequence — a bent, cracked, or worn Choke Arm causes incomplete choke closure, hard starting, and rough running until the engine reaches operating temperature.
The Choke Arm is the mechanical link between the choke actuator and the choke plate inside the carburetor. When you move the choke control — whether by hand or through a throttle assembly — the Choke Arm translates that motion into rotation of the choke shaft, which opens or closes the choke plate to richen or lean the air-fuel mixture. A damaged or distorted arm breaks that linkage, leaving the choke plate in a fixed position and making reliable starting and smooth warm-up impossible. Replacing it with a correct OEM part restores the precise movement the carburetor was designed around.
