16100-Z9L-811 Carburetor Replacement Compatible with Honda GCV170 GCV170LA GCV160 HRN216 HRX217 Engine Carb for Lawn Mower, Pressure Washer, Generator, Push Sprayer

What It Is

This is a replacement carburetor for Honda GCV160/GCV170 engines, commonly found on lawn mowers (HRN216, HRX217), pressure washers, generators, and push sprayers. It meters fuel and air into the engine’s combustion chamber—if your engine won’t start, stalls, or runs rough after cleaning the fuel system, this part often fixes it.

Fitment & Compatibility

Engine models: GCV160, GCV170, GCV170LA.
Machine models: HRN216, HRX217 (and any equipment using those engines).
What to check before buying:

• Confirm your engine’s model number (stamped on a metal tag near the spark plug or on the valve cover).
• This is a non-OEM (aftermarket) part—fit is identical to OEM Honda 16100-Z9L-811, but material quality may vary.
• Measure the mounting flange bolt spacing (center-to-center) to ensure it matches your engine’s intake manifold.
• Verify your engine has a fixed-jet carb (no adjustable main jet)—most GCV160/170 use a non-adjustable design.
• Not compatible with GCV135, GCV190, or GX series engines.

Key Things to Know

• Quality: Aftermarket carb—works fine for most users, but some report needing to clean out debris or adjust the float height out of the box.
• Installation difficulty: Moderate. Requires removing the air filter, fuel line, and two bolts. Have a small screwdriver and a 10mm socket ready.
• Common gotchas:
  • The fuel line grommet can be brittle on older engines—replace it if it leaks.
  • The gasket included is often thin; use a thin layer of gasket sealant if you see air leaks.
  • You may need to prime the carb (squeeze primer bulb 10-15 times) after installation to fill the bowl.
• Tuning: No adjustment screws—it’s preset. If it runs lean or rich, you may need to swap the main jet from your old carb.

Should You Buy It

If your Honda GCV160/170 engine won’t start or runs poorly despite fresh gas and a clean fuel filter, this is a cheap, effective fix. It’s ideal for DIYers who want to save $50–$80 over an OEM carb. Skip it if you need exact OEM reliability for commercial use—go with a genuine Honda carb instead.
