16100-Z8B-901 BB76A A Carburetor (Auto Choke) Carburetor GCV160 Carburetor for Honda HRS216K5 HRR216K9 with specific models of GCV160LA0 GCV160LA1 Engines

What It Is

This is an OEM Honda carburetor with auto choke, designed for GCV160 engines used on select Honda walk-behind mowers. It replaces the fuel delivery and choke system in one assembly.

Fitment & Compatibility

Before buying, confirm your engine’s model number (e.g., GCV160LA0 or GCV160LA1) – this carb fits those specific variants, not all GCV160 engines. Mower models include HRS216K5 and HRR216K9, but double-check your mower’s serial number against Honda’s compatibility chart. This is an OEM Honda part (16100-Z8B-901), not an aftermarket copy, so it should bolt directly to the stock intake manifold and air filter housing. Measure your existing carb’s mounting bolt spacing (typically 50mm center-to-center) and ensure the auto-choke wiring connector matches your harness. No deck size or blade check needed – this is purely engine-side.

Key Things to Know

• Auto choke setup: The carb comes with a wax-element auto choke. If your mower’s harness or wiring is damaged, the choke won’t function properly – test continuity before installation.
• Installation difficulty: Moderate. You’ll need to remove the air filter, fuel line, and throttle cable. Expect 30–60 minutes for a first-timer. Have a new gasket (often sold separately) and fresh fuel.
• Quality concerns: At $17, this is unusually cheap for an OEM Honda carb – possibly old stock or a closeout. The 3.0 rating with only 2 reviews suggests limited feedback. Verify the part isn’t a counterfeit by checking the Honda hologram and packaging.
• Common gotcha: The auto choke’s wax element can fail if the engine overheats or sits for years. If your mower runs rich or won’t start after install, the choke may be stuck open/closed.

Should You Buy It

If you own a confirmed-compatible Honda mower with a GCV160LA0/LA1 engine and want a direct OEM replacement at a bargain price, this carb is worth the risk – but only if you’re comfortable troubleshooting the auto choke. For other GCV160 variants or if you prefer a guaranteed-newer part, skip it and buy a current Honda-spec carb for $30–50.
