CARRBIA 16100-Z8B-901 Carburetor (BB76A A) Carb Assembly w/Tune up Kit Compatible with Honda Fits specific Engines HRR216K10 HRR216K11 HRR216K9 HRS216K5 HRS216K6 HRS216K7 Lawnmowers

What It Is

This is a complete carburetor assembly (OEM part number 16100-Z8B-901) with a tune-up kit, designed for Honda GCV160/GCV190 engines used in specific HRR216 and HRS216 series lawnmowers. It replaces the factory carburetor and includes gaskets, fuel filter, and spark plug for a full fuel system refresh.

Fitment & Compatibility

• Engines: Honda GCV160 (on HRR216K9, K10, K11) and GCV190 (on HRS216K5, K6, K7).
• Mowers: HRR216K9, HRR216K10, HRR216K11, HRS216K5, HRS216K6, HRS216K7.
• Check before buying: Confirm your mower’s model number (stamped under the seat or on the rear frame) and engine serial number. This is an aftermarket part (not OEM Honda), so verify that your original carburetor has the same mounting flange, primer bulb location, and fuel line diameter (typically 5/16”).
• Not compatible with: HRR216K8 or earlier, push mowers with Honda GCV160/190 engines that use a different carburetor base (e.g., HRR216VKA, HRR216TDA). Always cross-reference your engine’s carburetor mounting bolt pattern.

Key Things to Know

• Quality: Aftermarket part; reviews note it works well, but some units may need minor adjustment to the float height (check with a caliper before install).
• Installation: Moderate difficulty—requires removing the air filter housing, fuel lines, and throttle cable. Expect 30-60 minutes. Fuel line clamps may be brittle; have replacements ready.
• Common gotcha: The included tune-up kit’s spark plug may not match your engine’s heat range—use an OEM Honda spark plug (NGK BPR6ES) for best results.
• Fuel system prep: Clean the fuel tank and replace the fuel line if it’s old or cracked; debris from the tank is the #1 cause of new carb failure.

Should You Buy It

Buy this if you have a compatible HRR216 or HRS216 mower with a clogged or worn-out carburetor and want a complete, cost-effective replacement kit. It’s ideal for DIYers comfortable with basic engine work and who don’t need OEM parts for warranty or strict reliability. If you have a different Honda GCV engine model, verify fitment first to avoid returns.
