The Honda 16631-ZL8-850 Stop Lever is a genuine OEM component designed for GC135, GC160, and GC190 horizontal shaft engines and EN2000 and EN2500 generators. As a direct Honda OEM replacement, this part carries the same specifications as the lever it replaces, ensuring correct operation with no guesswork on fit or function. Confirm your model and serial number against the fitment table before ordering — Honda supersedes parts at serial breaks, and verifying part number 16631-ZL8-850 against your unit is the surest way to get the right part.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Stop Lever meets the same specifications as the original, so throttle and engine-stop behavior stays exactly as intended.
- Correct Lever Geometry — the pivot points, travel range, and lever profile match the original, allowing the stop mechanism to engage and release cleanly without binding or slop.
- Broad Fitment — fits GC135, GC160, and GC190 horizontal shaft engines, as well as EN2000 and EN2500 generators, including units powered by the GC-series engine.
- Check Your Serial Number — Honda updates parts mid-production run, so cross-reference your machine's serial number with the fitment table to confirm part number 16631-ZL8-850 is correct for your specific unit.
The Stop Lever is a key control component in the throttle and engine-stop system. It translates operator input — whether from a kill switch, a throttle bail, or a linked control — into a mechanical signal that cuts engine operation when released or actuated. When this lever is worn, bent, or broken, the engine may fail to stop reliably on command, or the throttle linkage may not return to the correct idle or shutoff position. Replacing a damaged Stop Lever restores the crisp, predictable control response the engine and the equipment it powers depend on.
