Honda 16100-Z8B-901 Carburetor Kit with Gaskets

What It Is

The Honda 16100-Z8B-901 is an OEM carburetor rebuild kit designed to restore fuel delivery on Honda GCV160 and GCV190 small engines, commonly found on push mowers, pressure washers, and generators.

Fitment & Compatibility

• Engines: Fits Honda GCV160 (including variants like GCV160LA0, GCV160LA1) and GCV190 engines. Check your engine’s model code (stamped on the blower housing or valve cover) to confirm.
• Machines: Works with Honda HRR216, HRX217, and HRX217HYA mowers, plus other equipment using these engines. Not for GXV120, GXV140, or GX series.
• OEM vs Aftermarket: This is a genuine Honda kit. Aftermarket kits exist but often lack the precise gasket thickness and jet sizing needed for reliable operation.
• What to check before buying:
  • Engine model/serial number (e.g., GCV160LA0 S2A-1234567).
  • Carburetor mounting bolt pattern (two or four bolts – this kit fits both).
  • Existing carburetor gasket condition; if warped or cracked, you may need a separate base gasket.
• Measurements: Kit includes main jet, pilot jet, float bowl gasket, and throttle shaft seals. Float and needle valve are not included – inspect your original parts.

Key Things to Know

• Quality: OEM Honda parts ensure correct fuel metering and long life. Aftermarket kits may cause surging or hard starts.
• Installation difficulty: Moderate. You’ll need a small flathead screwdriver, Phillips head, and carburetor cleaner. Expect 30–60 minutes for a first-timer.
• Common gotchas:
  • The float bowl gasket must seat perfectly; overtightening the bowl screw can warp it.
  • The throttle shaft seals are fragile – lubricate with WD-40 before pressing in.
  • Do not reuse old gaskets – even if they look good, they compress and leak.
• Note: This kit does not include a carburetor assembly or fuel line. If the carb body is cracked or warped, replace the entire carburetor.

Should You Buy It

If your Honda GCV160 or GCV190 engine is hard-starting, surging, or leaking fuel, this kit is the right fix. It’s ideal for DIYers comfortable with carburetor disassembly who want OEM reliability. For a complete carburetor replacement or non-Honda engines, look elsewhere.
