What It Is

This is an aftermarket carburetor that replaces the OEM Honda 16100-Z8B-901. It fits Honda GCV160 engines found on push mowers (HRR216 series), pressure washers, and other small power equipment needing a reliable fuel delivery fix.

Fitment & Compatibility

Before buying, confirm three things:

• Engine model: Must be Honda GCV160LA0, GCV160LA1, or any GCV160 variant. Check the engine sticker (under the fuel tank or on the shroud).
• Machine models: Fits HRR216K9/K10/K11, HRS216K5/K6/K7 push mowers, and pressure washers with the same engine.
• OEM vs aftermarket: This is not a Honda OEM part, but it is a direct bolt-on replacement. Verify your existing carburetor’s mounting hole spacing (center-to-center) matches 60mm.
• Measurements: Overall height ~4.5”, flange width ~2.5”. Compare to your old unit before ordering.

Don’t buy if your engine is a GCV160 (non-LA suffix) with a different fuel shutoff or primer bulb location—this carb uses a top-mounted primer and fixed main jet.

Key Things to Know

• Quality vs OEM: At $14.59, it’s 1/3 the price of a Honda OEM carb. Works fine for most users, but the internal jetting may be slightly leaner—expect potential idle issues on some machines.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, disconnect the throttle/governor linkage, and swap the fuel line. Budget 30-45 minutes.
• Common gotchas: The included gasket may be thin—use a dab of silicone or add a second gasket to prevent vacuum leaks. Also, the choke linkage can be stiff; lubricate with WD-40 before fitting.
• Pre-install check: Blow out all ports with compressed air—debris from manufacturing is common. Adjust the idle mixture screw (if present) to 1.5 turns out as a baseline.

Should You Buy It

If you’re on a budget and comfortable with basic small-engine repair, this is a solid value. It’s ideal for reviving a non-running mower or pressure washer with a gummed-up OEM carb. For commercial use or if you want zero hassle, spend more on a genuine Honda unit. Otherwise, this gets the job done for most homeowners.
