The Honda 16500-ZH7-810 Remote Control Assembly is a genuine OEM component designed for GX120 horizontal shaft engines and WP20 and WP30 water pumps. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring an exact match for throttle and choke control linkage geometry. This assembly is the correct replacement for GX120 engines and the WP20 and WP30 water pumps — confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks.
Key Features
- Genuine Honda OEM Quality — factory-sourced with correct linkage geometry and cable routing to deliver consistent throttle and choke response on GX120 engines and WP20 and WP30 water pumps.
- Direct Replacement Fit — this assembly matches the original mounting points and control cable interface, so installation follows the same steps as the factory unit with no modification needed.
- Broad Fitment Coverage — designed for GX120 horizontal shaft engines as well as WP20 and WP30 water pumps, including multiple production serial ranges.
- Check Your Serial Number — Honda updates part numbers at serial breaks; verify your machine's serial number against the compatibility table to confirm this is the correct assembly for your unit.
- Restored Engine Control — a worn or damaged remote control assembly causes erratic throttle response, difficulty holding governed speed, and unreliable choke operation; this replacement restores precise operator control.
The Remote Control Assembly is the external throttle and choke control unit that links the operator's throttle lever to the engine's carburetor. It translates cable movement into precise adjustments of fuel and air delivery, allowing the engine to be governed and started correctly from the operator's position. When this assembly wears, binds, or breaks, the engine loses reliable speed control and can become difficult to start or run at a steady governed speed under load.
