BlueStars GCV170 Carburetor 16100-Z9L-811 - For Honda GCV 170 GCV170LA HRN216 GCV200LA HRX217 HRX217K6 G5B G5BR S3B 7 Engines Lawn Mowers with Air Filter 16100-Z9M-811

What It Is

This is a complete carburetor assembly for Honda GCV170, GCV200, and GCV200LA engines, commonly found on HRN216, HRX217, and HRX217K6 mowers. It replaces the OEM part 16100-Z9L-811 and includes an air filter, making it a drop-in replacement for a clogged or failing carburetor.

Fitment & Compatibility

• Engines: Honda GCV170, GCV170LA, GCV200LA, and related G5B, G5BR, S3B, and 7-series engines.
• Mowers: HRN216, HRX217, HRX217K6 (and similar HRX models with these engines).
• OEM Reference: Directly replaces Honda part 16100-Z9L-811 and 16100-Z9M-811.
• Check before buying: Confirm your engine model number (stamped on the engine shroud or valve cover). Also verify the carburetor mounting bolt pattern (two bolts, 60mm center-to-center) and fuel line diameter (5/16" ID). This carb is aftermarket, not Honda OEM—dimensions and gasket fit are identical, but the plastic bowl and float may differ slightly in material feel.

Key Things to Know

• Quality: Aftermarket carb; fine for casual use but may need slight float adjustment or gasket trimming on some units. Some users report a slight idle difference vs. OEM.
• Installation: Moderate difficulty. Requires removing the air filter housing, fuel line, and two mounting bolts. Clean the mounting surface and use the included gasket. No special tools needed beyond a screwdriver and pliers.
• Common gotchas: The included air filter may be lower quality than OEM—consider reusing your old filter if it’s clean. Also, check the fuel line for cracks; old lines may leak after reconnection.
• Warranty: No brand warranty; returns handled by seller (BlueStars). Test-fit before final assembly.

Should You Buy It

This is a solid budget option if your original carburetor is gummed up or leaking and you don’t want to spend $60+ on a Honda OEM unit. It works best for homeowners with a single mower who are comfortable with basic engine work. Avoid if you need exact OEM performance, run the mower daily commercially, or want a guaranteed long-term seal—go OEM for those cases.
