What It Is

This is a complete aftermarket carburetor assembly designed for Honda GCV160 and GC135/GC160 engines, commonly used on walk-behind mowers like the HRB216, HRS216, HRT216, and HRZ216. It replaces OEM part numbers 16100-ZM0-804, 16100-ZM0-802, 16100-Z0L-023, and 16100-Z0L-003.

Fitment & Compatibility

Before buying, verify your engine model (stamped on the engine shroud or valve cover—e.g., GCV160A, GCV160LA, GCV160LA0, GCV160LE) and confirm it matches one listed. This carburetor is for horizontal-shaft Honda engines only (not vertical-shaft). Check the gasket and mounting flange pattern—this unit should bolt directly to the intake manifold. If your mower has a primer bulb or auto-choke system, confirm the linkage style matches; some aftermarket units require reusing your original choke/spring. Measure the fuel line diameter (typically 5/16” or 1/4”) to ensure a snug fit. This is an aftermarket part, not OEM Honda—tolerances and materials may differ slightly.

Key Things to Know

• Quality varies – At $15.99, this is a budget carb. Expect plastic or pot-metal components; some users report needing to clean out debris or adjust the float height out of the box.
• Installation is moderate – You’ll need basic tools (screwdrivers, pliers, socket set) and about 30 minutes. Watch for small springs and linkages that can pop off easily.
• Common gotcha – The gasket included may be thin or poorly cut. Use a thin layer of gasket sealant or reuse your OEM gasket if it’s in good shape.
• Tuning required – After installation, you may need to adjust the idle mixture screw (if present) and throttle cable tension for smooth operation. A dirty fuel tank or old gas will quickly clog a new carb.

Should You Buy It

This is a good low-cost fix if your original carb is clogged, warped, or leaking and you’re comfortable with basic small engine repair. It works best as a quick replacement for a non-running mower, but if you want long-term reliability or exact OEM fit, spend more on a genuine Honda carb.
