GCV170LA Carburetor Tune Up Kit for Honda GCV170 HRN216VKA HRN216 Lawn Mower 16100-Z9L-811

What It Is

This is a genuine Honda carburetor tune-up kit designed to restore fuel delivery and starting performance on Honda GCV170-powered lawn mowers, specifically the HRN216VKA and HRN216 models. It includes the gaskets, seals, and fuel components needed to rebuild or replace the carburetor after fuel system issues like clogging, hard starting, or rough idling.

Fitment & Compatibility

• Exact fit for: Honda GCV170LA engines used on HRN216VKA and HRN216 mowers.
• OEM part number: 16100-Z9L-811 – this is Honda’s genuine kit, not an aftermarket substitute.
• Check before buying: Confirm your mower’s engine model (GCV170LA) is stamped on the engine shroud or manual. The kit fits only this specific carburetor variant; it will not work on GCV160 or GCV190 engines.
• Deck size irrelevant: Compatibility is engine-based only; deck size (e.g., 21-inch) doesn’t affect fitment.
• Includes: Carburetor gaskets, bowl gasket, O-rings, fuel filter, and sometimes a new float needle – verify contents against your existing carburetor.

Key Things to Know

• Quality: Genuine Honda OEM – better fit and longer life than aftermarket kits, but priced higher.
• Installation difficulty: Moderate – requires removing the carburetor, cleaning the old fuel residue, and carefully reassembling. A shop manual or video guide helps.
• Common gotcha: The kit does not include the carburetor itself; it’s a rebuild kit. If your carb body is warped or corroded, you’ll need a full replacement.
• Fuel system prep: After installation, drain old fuel and use fresh gas to prevent immediate re-clogging. Also check the fuel line and tank for debris.

Should You Buy It

Buy this kit if you have a Honda GCV170LA mower with hard starting, stalling, or fuel leaks and want a reliable OEM fix. It’s ideal for DIYers comfortable with carburetor work who prefer genuine parts over cheaper aftermarket alternatives. Skip it if you need a complete carburetor assembly or if your engine is a different Honda GCV series.
