GCV200 Carburetor for Honda HRX217 K6 Lawn Mower 16100-Z9M-811 Carburetor for Honda GCV200LA G5B GCV200LA G5BR GCV200LA S3C GCV200LA S3L Engine with GCV 200 Air Filter Fuel Filter Tune up Kit

What It Is

This is a complete carburetor assembly designed for Honda GCV200 engines, commonly found on HRX217 K6 mowers and similar models. It replaces the OEM Honda part 16100-Z9M-811 and includes the carburetor, gaskets, air filter, fuel filter, and a tune-up kit—everything needed to restore fuel delivery and engine performance.

Fitment & Compatibility

Check your engine model – This carburetor fits Honda GCV200LA G5B, G5BR, S3C, and S3L engines. It does not fit GCV190, GCV160, or GCV200 engines with different suffix codes. Confirm your mower model – Works with HRX217 K6, K5, K4, and K3 models, but verify your deck size (21-inch) and year range (2015–2020). OEM vs. aftermarket – This is an aftermarket replacement, not genuine Honda. Expect minor fit differences (e.g., gasket thickness). Measure first – Compare the new carburetor’s mounting flange bolt spacing and fuel inlet orientation to your old unit. If your engine has a plastic or metal intake manifold, ensure the gasket matches.

Key Things to Know

• Quality is good for the price – Most users report it works “out of the box,” but a few note the float height may need adjustment for optimal idle.
• Installation difficulty – Moderate. You’ll need a 10mm socket, screwdriver, and pliers. Expect 30–60 minutes. Remove the air filter housing, disconnect fuel line and throttle linkage, then swap the carb.
• Common gotcha – The supplied fuel filter may be too long for some tanks; trim the hose or use the old filter. Also, the air filter element is foam—keep it oiled lightly for dust protection.
• Tune-up kit included – Replace the spark plug (check gap) and fuel filter at the same time for best results.

Should You Buy It

If you have a Honda HRX217 with a GCV200 engine and need a budget-friendly carburetor replacement that includes filters and gaskets, this is a solid choice. It’s not OEM-grade, but for the price, it reliably fixes surging, hard starting, or poor idle. Skip it if you demand exact factory tolerances or have a non-GCV200 engine.
