GCV170 Carburetor for Honda GCV 170 GCV170LA Engine HRN216 HRN216 PKA Lawn Mower Replace 16100-Z9L-811

What It Is

This is a direct-replacement carburetor for Honda GCV170 engines, commonly used on HRN216 push mowers and other Honda lawn equipment. It meters the fuel-air mixture into the engine cylinder, and this aftermarket version is built to replace the OEM Honda part 16100-Z9L-811.

Fitment & Compatibility

• Engine family: Honda GCV170, GCV170LA (check your engine’s model tag—usually stamped on the valve cover or blower housing).
• Mower models: HRN216, HRN216PKA (verify your mower’s model plate, typically under the rear flap or on the deck).
• OEM vs. aftermarket: This is not a Honda OEM part; it’s an aftermarket clone. It should bolt on with the same gaskets and linkages, but minor differences in jetting or casting are possible.
• Measurements: Before buying, confirm your carburetor’s mounting hole spacing and bowl diameter match. This unit is designed to fit the standard GCV170 intake manifold and air filter housing.
• What to check: Your existing carburetor’s part number (stamped on the side) and that your mower’s throttle/choke linkage style matches (most GCV170 engines use a single cable or rod setup).

Key Things to Know

• Quality variance: Aftermarket carburetors often have slightly different jet sizing than OEM. If your mower runs rich or lean, you may need to swap the main jet from your old carb.
• Installation difficulty: Moderate—requires removing the air filter housing, fuel line, and linkage. Expect 20–40 minutes. Have a clean workspace to avoid debris.
• Common gotcha: The gasket included may be thinner or thicker than OEM. Use the original gasket if the new one causes leaks or poor sealing.
• Fuel system prep: Always clean or replace the fuel filter and drain old fuel before installation. Debris in the tank can quickly clog the new carburetor.

Should You Buy It

This is a solid budget fix if your original GCV170 carburetor is clogged, warped, or leaking beyond repair. It’s right for DIYers who are comfortable with basic engine work and don’t mind occasional tuning. If you need exact OEM performance or warranty coverage, stick with the Honda 16100-Z9L-811—but for most homeowners, this will get your mower running smoothly again.
