Genuine HONDA 16600-Z8D-840 GCV160 GCV190 HRR216 HRX217 Engine Choke Control Assembly New OEM 16600-Z1L-840

What It Is

The Genuine Honda 16600-Z8D-840 is the OEM choke control assembly for GCV160 and GCV190 engines, commonly found on Honda HRR216 and HRX217 walk-behind mowers. It controls the choke plate position for cold starts, replacing a worn or broken choke lever/cable assembly.

Fitment & Compatibility

Before buying, verify your engine model (GCV160 or GCV190) and mower deck series (HRR216 or HRX217). This part supersedes the older 16600-Z1L-840, so it fits all revisions of those engines. Check the choke lever’s mounting hole spacing (approx. 1.5” center-to-center) and cable length (roughly 12” from bracket to lever). It will not fit GCV135, GCV200, or any non-Honda engine. If your mower has a plastic choke lever that snaps into the control panel, this assembly replaces the entire unit—not just the lever knob.

Key Things to Know

• OEM quality, no guesswork – This is a genuine Honda part, not an aftermarket copy. Expect correct plastic thickness, spring tension, and cable routing.
• Moderate installation – You’ll need to remove the air filter cover and carburetor shroud to access the choke cable clip. A 10mm socket and Phillips screwdriver are required; plan 20–30 minutes.
• Common gotcha – If the choke plate itself is stuck (not just the lever), this assembly won’t fix it. Check that the plate moves freely before buying.
• Cable routing matters – Route the cable exactly as the old one was. Kinking it will cause binding or incomplete choke closure.

Should You Buy It

If your Honda mower’s choke lever is loose, broken, or the cable is frayed, this OEM assembly is the correct fix. It’s a direct replacement for GCV160/GCV190 engines on HRR216 and HRX217 decks, and the price is fair for genuine quality. Skip it if the choke plate itself is seized or if your engine is a different model.
