GCV170 Carburetor for Honda GCV170LA GCV200LA HRX217K6 HRN216 Lawn Mower Engines 16100-Z9M-811 16100-Z9L-811 Tune up Kit

What It Is

This is a complete carburetor assembly for Honda GCV170 and GCV200 series engines, commonly found on HRX217K6 and HRN216 walk-behind mowers. It replaces OEM part numbers 16100-Z9M-811 and 16100-Z9L-811, delivering fuel to the engine for starting and running.

Fitment & Compatibility

Before buying, confirm your engine model (GCV170LA, GCV200LA, or similar) by checking the sticker on the engine shroud—not the mower deck. This carb fits Honda HRX217K6 and HRN216 mowers with those engines, but not older HRX217 models with GCV190 or GXV160 engines. It’s an aftermarket replacement for the OEM Honda carb; measurements match the original, but always verify the throttle linkage and gasket pattern matches your existing carb. If your mower has a plastic fuel bowl bolt, this kit includes a metal replacement—check that your fuel line and primer bulb are compatible.

Key Things to Know

• Quality variance: At $20, this is a budget aftermarket carb. Some units may need minor adjustment of the idle mixture screw (if adjustable) or have slightly looser tolerances than OEM. Expect to clean out any shipping debris.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, disconnect the fuel line (have a clamp handy), and swap the carb. Reuse your old gaskets if the new ones are thin or poorly cut.
• Common gotcha: The supplied metal fuel bowl bolt can crack if overtightened—hand-tighten + 1/8 turn only. Also, the primer bulb may be stiffer than OEM; if it doesn’t seat fully, the engine won’t prime.
• Tune-up kit note: This includes a carburetor, gaskets, and a fuel filter. It does not include a spark plug or air filter—buy those separately for a full tune-up.

Should You Buy It

Right for DIY owners with a Honda GCV170/GCV200 engine who want a cheap, quick fix for hard-starting or surging issues—especially if the original carb is clogged beyond cleaning. Not ideal if you demand OEM reliability for professional use; opt for the genuine Honda carb ($60+) if you need zero hassle. For occasional homeowners, this is a solid value at $20.
