The Honda 16562-ZM0-000 Throttle Return Spring is a genuine OEM component designed for GCV160, GCV190, and GSV190 vertical shaft engines, as well as HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers. As a direct Honda OEM replacement, this spring is manufactured to the same specification as the part that left the factory, ensuring the throttle behaves exactly as intended. Verify your machine's serial number against the fitment table before ordering, as Honda updates parts at production breaks and the correct spring may vary by build date.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this spring delivers the correct tension and return speed the throttle linkage was engineered around, not an approximation of it.
- Correct Throttle Snap — a throttle return spring that has lost tension causes sluggish or incomplete throttle closure, leading to erratic idle and poor governor response; this replacement restores crisp, immediate return action.
- Broad Fitment — covers GCV160, GCV190, and GSV190 engines, including HRB216, HRB217, HRC216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers.
- Check Your Serial Number — Honda supersedes components at specific production points; confirm your machine's serial number against the compatibility table to ensure this is the right spring for your unit.
The throttle return spring pulls the throttle plate or throttle lever back to its idle or closed position the moment the operator releases the control. Without adequate spring tension, the throttle may hang open rather than snap back, causing the engine to over-rev, hunt at idle, or fail to respond predictably to the governor. A worn or broken spring is a common cause of uneven engine speed on walk-behind mowers and the vertical-shaft engines that power them, and replacing it is one of the quickest ways to restore normal throttle feel and governor stability.
