16950-ZM0-003 Petcock Kit -16100-Z0L-876 Carburetor for Honda GCV160A0 GCV160LA GCV160LA0 HRR216 Lawn Mower Engines Carb with 12-041-01-S Air Filter

What It Is

This is a combined fuel shut-off valve (petcock kit, part 16950-ZM0-003) and carburetor assembly (part 16100-Z0L-876) for Honda GCV160 engines, commonly found on HRR216 push mowers. It replaces the original fuel valve and carburetor in one kit, also includes a 12-041-01-S air filter.

Fitment & Compatibility

• Engine models: Honda GCV160A0, GCV160LA, GCV160LA0 (check your engine’s model code stamped on the blower housing).
• Mower models: HRR216 series (e.g., HRR216K9, HRR216VKA) – verify your deck size (21-inch typically) isn’t the issue; the engine fit is critical.
• OEM vs aftermarket: This is genuine Honda, so it matches factory specs – no adapter or modification needed.
• Measurements: The petcock has a standard 1/4-inch fuel line barb; the carburetor flange matches the GCV160 intake manifold. Check your old carb’s gasket pattern – this uses the same 4-bolt pattern and choke linkage.
• Before buying: Confirm your mower uses the GCV160 engine (not GCV190 or GCV135). Also ensure your fuel line is flexible enough to connect to the new petcock without kinking.

Key Things to Know

• Quality: Genuine Honda – better than most aftermarket carb replacements; the petcock is metal, not plastic, and has a replaceable O-ring.
• Installation difficulty: Moderate – you’ll need to drain fuel, remove the old carb and petcock, transfer the throttle/choke cables, and reinstall. Expect 30–60 minutes.
• Common gotcha: The new carb comes with a bowl gasket pre-installed, but you must check the float height (should be 14.5mm) if the engine floods. Also, the petcock’s fuel outlet faces downward – ensure your fuel line isn’t pinched by the mower frame.
• Air filter included: The 12-041-01-S filter fits the GCV160 air box – replace it with the carb to save a trip.

Should You Buy It

If your Honda GCV160-powered mower won’t start due to a clogged carb or a leaking petcock, this is the simplest, most reliable fix. It’s a direct OEM replacement that costs less than buying the carb and petcock separately, and the included air filter is a bonus. Ideal for DIYers who want a one-and-done solution without fussing with aftermarket carb adjustments.
