SYOWADA GCV170 Carburetor Replacement for Honda GCV170LA GCV200LA HRX217 HRN216K6 Series Lawn Mower 16100-Z9L-811 Carb Tune up Kit

What It Is

This is a complete carburetor replacement kit for Honda GCV170 and GCV200 series engines, commonly found on HRX217 and HRN216K6 mowers. It includes the carburetor, gaskets, fuel line, and filter—everything needed for a full tune-up.

Fitment & Compatibility

• Engine models: Honda GCV170LA, GCV200LA, and any GCV170/GCV200 variant (check your engine’s model number sticker).
• Mower models: HRX217 series (e.g., HRX217HYA, HRX217K6) and HRN216K6 series (e.g., HRN216VKA).
• OEM part cross-reference: Replaces Honda 16100-Z9L-811 (OEM carb) and 06111-Z9L-810 (tune-up kit).
• What to measure: OEM carb mounting bolt spacing is ~40mm center-to-center. Verify your fuel line inner diameter matches the kit’s included line (usually 5/16”).
• Note: Not compatible with GCV160, GCV190, or non-LA/LA-series engines without checking bolt pattern and throttle linkage.

Key Things to Know

• Quality: Aftermarket carb, not OEM Honda. Many users report it works fine, but some may need minor adjustment to the idle mixture screw (turn 1.5 turns out as a starting point).
• Installation difficulty: Moderate. You’ll need a socket set, screwdriver, and patience to transfer the throttle cable and choke linkage from the old carb. Expect 30-60 minutes.
• Common gotchas: The included gaskets may be slightly thinner than OEM—use a dab of grease to hold them in place during reassembly. If the engine runs rich, check the float height (should be ~12mm from gasket surface).
• Fuel system prep: Drain old gas, clean the fuel tank, and replace the fuel filter. Stale fuel or debris will quickly clog the new carb.

Should You Buy It

If your Honda mower is hard-starting, surging, or won’t run at all and cleaning the OEM carb didn’t help, this kit is a cost-effective fix. It’s best for DIYers comfortable with basic engine work who want a quick tune-up without paying $60+ for an OEM carb. Avoid if you need exact OEM fitment or if your engine has a different mounting pattern.
