16100-Z0Y-813 Carburetor Fit for Honda HRB216 HRR216 HRS216 HRT216 HRS216 HRS216K1 GCV160 GCV160A GCV160LA

What It Is

This is an aftermarket carburetor assembly designed to replace the OEM Honda 16100-Z0Y-813. It fits Honda HRB216, HRR216, HRS216, HRT216, and HRS216K1 walk-behind mowers, as well as GCV160, GCV160A, and GCV160LA engines. It delivers the air-fuel mixture to the engine for starting and running.

Fitment & Compatibility

• Engine model is key: Confirm your mower uses a GCV160 engine (check the engine label, not just the mower deck model).
• OEM vs aftermarket: This is not a genuine Honda part. It’s a low-cost replacement. Expect minor fit differences—some users report needing to adjust the float height or clean out debris from the fuel passages before installation.
• Measurements: The carburetor body, gasket, and mounting bolt pattern match the OEM. The fuel inlet and choke linkage are compatible with the GCV160’s air filter housing and throttle cable.
• What to check before buying: Verify your engine’s model number (e.g., GCV160A) and the carburetor gasket shape. If your mower uses a different air filter base (some HRR216 models vary), the choke linkage may not align perfectly.

Key Things to Know

• Quality is variable: This is a budget aftermarket carb. It may need internal cleaning (blow out passages with compressed air) to remove manufacturing debris. Expect to replace gaskets and possibly the bowl gasket.
• Installation difficulty: Moderate. You’ll need basic hand tools (socket set, screwdrivers). The hardest part is aligning the throttle and choke linkages. Expect 30–60 minutes if you’re handy.
• Common gotcha: The carburetor bowl drain screw may be plastic and strip easily. Use a proper screwdriver and don’t overtighten. Also, the fuel line may be a tight fit—soak the line in hot water to soften it.
• No adjustment screws: This carburetor is non-adjustable (fixed jet). If your engine runs lean or rich, you’ll need to clean or replace the carburetor, not tune it.

Should You Buy It

If you need a quick, cheap fix for a GCV160 mower that won’t start or runs poorly, this carburetor is a solid budget option—especially if you’re comfortable with minor tweaks. It’s not a long-term OEM-quality solution, but at this price, it’s worth trying before spending $50+ on a genuine Honda unit. Avoid if you want a perfect, drop-in fit or if your mower has a different engine (like GCV190).
