What It Is

This is an aftermarket carburetor designed for Honda GCV160, GCV160A, GCV160LA, and GCV160LAO engines, commonly found on HRB216, HRS216, HRZ216, and HRT216 walk-behind mowers. It replaces OEM part numbers 16100-ZMO-804 and 16100-ZOL-023, supplying the correct air-fuel mixture to keep the engine running.

Fitment & Compatibility

Before buying, confirm your engine model is GCV160, GCV160A, GCV160LA, or GCV160LAO (check the stamped label near the fuel tank or under the air filter cover). This carb fits mower decks from 21 to 22 inches on HRB, HRS, HRZ, and HRT series. It is NOT compatible with GCV190, GCV135, or older Honda engines like GXV120. Measure the mounting bolt spacing (approx. 60mm center-to-center) and verify your throttle linkage style—this unit uses a fixed jet and a single fuel line (5/16” ID). If your mower has a primer bulb, this carb includes it; if not, you may need to swap your old primer.

Key Things to Know

• Quality variance: Aftermarket carb—works well for most, but a small percentage report sticky float or misaligned gaskets. Inspect the gasket and float movement before installing.
• Installation difficulty: Moderate. Requires removing air filter housing, fuel line (pinch or clamp), and two mounting nuts. Expect 20-40 minutes if you’ve done it before.
• Common gotcha: The included gaskets may be thinner than OEM. Use a thin smear of fuel-resistant sealant on the intake gasket to prevent vacuum leaks.
• Tuning: No adjustment screws—this is a fixed-jet carb. If it runs rich or lean after install, clean the fuel system (tank, line, filter) first, as debris is often the real issue.

Should You Buy It

If your Honda GCV160-powered mower stumbles, won’t start, or runs rough after sitting, this $16.99 carb is a cost-effective fix—especially if you’ve already tried cleaning the stock carb without success. It’s not OEM quality, but for the price and with a 4.5-star average, it’s a solid value for DIYers who want a quick, drop-in replacement rather than rebuilding the original.
