What It Is

This is a complete aftermarket carburetor assembly for Honda GCV160 engines, commonly used on HRT216, HRS216, HRB216, HRR216, and HRZ216 walk-behind mowers. It replaces multiple OEM Honda carburetor part numbers (16100-Z0L-023, 16100-ZM0-804, 16100-ZM0-802) and is designed to fix hard starting, surging, or stalling caused by old or clogged fuel systems.

Fitment & Compatibility

• Engine check first: This carburetor fits only Honda GCV160 engines (including GCV160a, GCV160LA0, GCV160LAO, GCV160LA, GCV160LE variants). It does not fit GCV190, GCV200, or any non-Honda engines.
• Deck size irrelevant: Fitment is based on the engine model, not the mower deck width. Confirm your engine’s model number (stamped on the engine shroud or near the spark plug).
• OEM vs aftermarket: This is an aftermarket replacement, not a genuine Honda part. It includes the carburetor body, gaskets, and bowl—but not the intake manifold gasket or fuel line. You may need to reuse or buy those separately.
• Direct bolt-on: Matches the original mounting pattern and throttle/choke linkages for the listed mower series. No modification required.

Key Things to Know

• Installation is straightforward with basic hand tools (screwdrivers, socket set). Clean the intake surface and replace the old gasket. Torque the mounting nuts evenly to avoid warping.
• Adjust the idle mixture screw after installation. Turn it in gently until it seats, then back out 1.5 to 2 turns as a starting point. Tune for best idle after engine warms up.
• Common gotcha: The aftermarket carb may have a slightly different fuel inlet angle. If your fuel line kinks, replace it with a short piece of 1/4-inch fuel line.
• Quality note: At $17.50, this is a budget part. Most users report it works well out of the box, but a small percentage may need the float height checked or a quick cleaning of internal passages.

Should You Buy It

If your Honda GCV160 mower is hard to start, runs rough, or won’t stay running, this carburetor is a cost-effective fix—especially if you’re handy with basic engine work. It’s ideal for DIY homeowners who want to avoid a $60+ OEM part or a trip to the shop. Not recommended for commercial use or if you require OEM-tolerance reliability.
