The Honda 16562-ZL8-000 Throttle Return Spring is a genuine OEM component designed for EN2000 and EN2500 generators and GC135 and GC160 horizontal shaft engines. As a direct Honda OEM part, it is manufactured to the same specification as the original, ensuring consistent throttle response and dependable operation across all covered applications. Honda supersedes parts at serial number breaks, so confirm your unit's serial number against the fitment table before ordering to be certain this is the correct spring for your machine.
Key Features
- Genuine OEM Throttle Control — manufactured by Honda to deliver the correct spring tension for consistent, repeatable throttle response on EN2000, EN2500, GC135, and GC160 equipment
- Direct OEM Replacement — built to original specifications, this spring installs in place of the worn or broken original without alteration
- Serial Number Verification Recommended — Honda updates part numbers at production breaks, so cross-reference your machine's serial number with the fitment table to confirm the correct application
- Restored Throttle Return Action — a failed or weakened spring causes the throttle to hang open or respond sluggishly, leading to erratic engine speed; replacing it restores crisp, controlled deceleration
The throttle return spring is a small tension spring in the throttle linkage that pulls the throttle plate or slide back toward the closed position whenever the operator releases the throttle control. It works against the opening force of the throttle mechanism and ensures the engine returns to idle promptly and reliably when the load is removed. When this spring weakens, breaks, or falls out of position, the throttle may stick open, causing the engine to run at uncontrolled speed, or it may fail to return to idle at all — both conditions require immediate attention before the equipment is put back into service.
