GCV170 Carburetor 16100-Z9M-811 for Honda GCV 170 GCV170LA HRN216 GCV200LA HRX217K6 Engines Tune Up Kit 16100-Z9L-811

What It Is

This is a complete carburetor replacement kit for Honda GCV170, GCV170LA, GCV200LA, and HRX217K6 engines. It’s designed for walk-behind mowers, pressure washers, and other small equipment using these Honda engines, replacing the factory carburetor (OEM part 16100-Z9M-811 or 16100-Z9L-811) when the original fails from clogged jets, sticky float, or worn gaskets.

Fitment & Compatibility

Check your engine model number – not just the mower brand. This fits Honda GCV170, GCV170LA, GCV200LA, and HRX217K6 engines. It will not fit GCV160, GCV190, or GCV135 engines. Look for a stamped metal tag on the engine shroud (near the spark plug) that says “GCV170” or similar.

OEM vs aftermarket – This is an OEM Honda part, not a generic. That matters for jet sizing and gasket fit. Aftermarket clones often have wrong jet diameters or leaky seals.

Measure the mounting bolt spacing – The carburetor base has two bolts 48mm apart center-to-center. If your current carb matches that, this will bolt up. Also verify the intake manifold gasket shape (rectangular, 2-bolt pattern).

Includes – Carburetor body, gaskets, mounting bolts, and sometimes a fuel filter. You may need a new spark plug or air filter separately.

Key Things to Know

• Quality – OEM Honda means correct jet sizes and float height. Expect reliable starting and no surging if installed correctly.
• Installation difficulty – Moderate. You’ll need a socket set, screwdrivers, and possibly pliers. The hardest part is removing the old carb without stripping bolts (use penetrating oil on stubborn ones).
• Common gotchas – The float bowl gasket must seat perfectly; overtightening cracks the plastic bowl. Also, the fuel line can be brittle – replace it if cracked. After installation, prime the bulb and check for leaks before starting.
• Tune-up kit – This replaces the carb only. For a full tune-up, buy a separate spark plug (NGK BPR6ES) and air filter. Don’t reuse old gaskets.

Should You Buy It

Buy this if your Honda GCV170/200 engine has hard starting, surging, or fuel leaks and you want a direct OEM replacement without guessing on jet sizes. It’s ideal for DIYers comfortable with basic engine work—skip it if you prefer a full tune-up kit with plug and filter, or if your engine model isn’t listed here.
