The Honda 16571-Z4H-000 Control Lever is a genuine OEM replacement designed for the GX120 horizontal shaft engine, WB20, WB30, WH15, and WH20 water pumps, and WDP20 and WDP30 diaphragm water pumps. As a Honda OEM part, it is manufactured to the same specifications as the original component it replaces, ensuring a direct, no-guesswork fit. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and more than one control lever variant may appear across this equipment range.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this control lever matches the original component's geometry and pivot action for consistent throttle and choke control response.
- Broad Equipment Compatibility — fits GX120 horizontal shaft engines as well as WB20, WB30, WH15, and WH20 centrifugal water pumps and WDP20 and WDP30 diaphragm water pumps, covering a wide range of Honda-powered equipment.
- Correct Lever Action — a worn or damaged control lever leads to imprecise throttle positioning, making it difficult to hold steady engine speed and reducing the operator's control over the machine it powers.
- Serial Number Verification Recommended — Honda issues part updates at specific serial breaks; check your machine's serial number against the compatibility table to confirm part number 16571-Z4H-000 is the correct lever for your unit.
The control lever is the mechanical link between the operator and the engine's throttle and choke circuits. It translates hand movement at the control panel or handle into precise cable and linkage motion, setting the engine's speed and fuel mixture for starting, running, and stopping. When the lever is bent, cracked, or worn at its pivot, it loses the positive detent or travel range needed to reach full-throttle or choke positions — causing hard starts, erratic speed, or a machine that will not shut down cleanly.
