Anxingo 16100-Z9L-811 Carburetor kit Replacement for Honda GCV170LA G5B G5BR S3B GCV200LA HRN216 HRX217K6 Lawn Mower

What It Is

This is an aftermarket carburetor kit designed to replace the OEM unit on Honda GCV170LA and GCV200LA engines, commonly found on HRN216 and HRX217K6 walk-behind mowers. It handles fuel metering and delivery to the engine—critical for starting, idling, and full-throttle performance.

Fitment & Compatibility

• Engine models: Fits Honda GCV170LA G5B, G5BR, S3B, and GCV200LA.
• Mower models: HRN216 (all variants), HRX217K6 (check your deck size; works with 21-22 inch decks).
• OEM crossover: Replaces Honda part number 16100-Z9L-811. Aftermarket—not OEM, so minor fit variations possible.
• Check before buying: Verify your engine’s model number (stamped on valve cover or shroud). Measure your carburetor’s mounting bolt spacing (typically 2.5 inches center-to-center). Ensure your mower uses a single-barrel, side-draft carb with primer bulb (common on GCV170/200). Does not fit GCV160 or GCV190 engines.

Key Things to Know

• Quality: Single review at 4.0—likely functional but not premium; inspect gaskets and o-rings for burrs before install.
• Installation difficulty: Moderate—requires removing air filter housing, fuel line, and throttle/governor linkages. Have a small screwdriver set and pliers ready.
• Common gotchas: The primer bulb may be slightly stiffer than OEM; expect a few extra primes on first start. Fuel line diameter is 5/16”—if your mower uses 1/4” line, you’ll need an adapter or different kit.
• Tuning: No adjustable jets—set idle speed via the throttle stop screw (factory setting ~2800 rpm). If it runs rich, check float height (should be 8.5mm from gasket surface).

Should You Buy It

Buy it if you need a budget fix for a hard-starting GCV170/200 mower and don’t mind a non-OEM part with slightly variable fit. Avoid if you want guaranteed plug-and-play or have a GCV160/190 engine—those require a different kit. For $15, it’s a low-risk first step before replacing the whole engine.
