The Honda 16112-Z5T-W01 Choke Arm is a genuine OEM replacement designed for GX240, GX270, GX340, and GX390 horizontal shaft engines, EB4000, EB5000, and EB6500 generators, EM4000, EM5000, and EM6500 generators, and HS1336 and HSM1336 two-stage snow blowers. As a direct Honda OEM component, this choke arm is manufactured to the same specification as the original, ensuring correct movement and positioning within the carburetor's choke circuit. Confirm your unit's serial number against the fitment table before ordering, as Honda periodically supersedes parts at specific serial breaks.
Key Features
- Genuine OEM Choke Control — Honda-sourced part engineered to deliver the correct choke plate travel and lever engagement that the carburetor depends on for accurate fuel metering at cold start.
- Broad Cross-Equipment Fit — a single part serving GX240, GX270, GX340, and GX390 horizontal shaft engines; EB and EM series generators including the EB4000, EB5000, EB6500, EM4000, EM5000, and EM6500; and HS1336 and HSM1336 two-stage snow blowers.
- Drop-In Replacement — matches the original mounting points and pivot geometry, so installation follows the same procedure as the part being replaced with no rework to surrounding components.
- Serial Number Verification Recommended — Honda supersedes carburetor components at production breakpoints; check your machine's serial number against the fitment table to confirm this is the correct arm for your build.
The choke arm is the mechanical link between the choke control and the choke plate inside the carburetor. When the operator activates the choke, the arm rotates the plate to restrict incoming air, enriching the fuel mixture and allowing the engine to fire reliably from cold. As the engine warms, the arm returns the plate to the open position to restore the correct air-to-fuel ratio for normal running. A worn, bent, or broken choke arm causes sluggish cold starts, rough running during warm-up, or a choke plate that will not fully open — each of which robs the engine of the clean throttle response and stable output that equipment operators depend on.
