16100-ZM0-804 Lawnmower Carburetor Kit, Replacement for Honda HRT216 HRR216 HRB216 HRS216 HRZ216, Replacement for Honda GCV160 GCV160A GCV160LA GCV160LE

What It Is

This is a genuine Honda carburetor kit (OEM part number 16100-ZM0-804) that replaces the complete carburetor assembly on select Honda HRT, HRR, HRB, HRS, and HRZ series walk-behind mowers, as well as GCV160 engines. It includes the carburetor body, gaskets, and necessary hardware for a direct swap.

Fitment & Compatibility

• Mower models: Fits Honda HRT216, HRR216, HRB216, HRS216, and HRZ216 series.
• Engines: Compatible with Honda GCV160, GCV160A, GCV160LA, and GCV160LE.
• What to check first: Verify your mower’s model number (stamped on the deck or engine shroud) and that it uses a GCV160 engine. This kit is a complete carburetor assembly, not a rebuild kit—no need to disassemble the old carb.
• OEM vs aftermarket: This is a genuine Honda part, not a generic substitute. OEM ensures exact fit and gasket alignment; aftermarket versions may require modification or fail sooner.
• Measurements: The carburetor mounting bolt spacing is standard for GCV160 engines; no special tools needed.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, screwdrivers) and about 30–60 minutes. Removing the air filter housing and fuel line is required.
• Quality: Genuine Honda construction—cast aluminum body, brass jets, and EPDM gaskets. Should last 3–5 seasons with regular fuel maintenance.
• Common gotchas:
  • The fuel line may be brittle; have a short length of 1/4-inch fuel line and clamps ready.
  • The throttle linkage spring is small and easy to lose—work over a tray.
  • If the mower has been sitting with old fuel, also replace the fuel filter and clean the tank to prevent debris from clogging the new carb.
• No adjustments needed: This is a bolt-on replacement; the factory settings are pre-calibrated for the GCV160 engine.

Should You Buy It

If your Honda mower with a GCV160 engine is hard-starting, surging, or won’t run despite cleaning the old carb, this genuine Honda kit is a reliable, direct fix. It’s ideal for DIY owners who want a no-guesswork replacement rather than a rebuild. Skip it if you’re comfortable disassembling and cleaning your existing carburetor—that’s cheaper but more labor-intensive.
