GCV160 Carburetor for Honda GCV160A GCV160LA GCV160LAO GCV160L Eengine Lawn Mower CarbHRB216 HRS216 Replace 116100-Z0L-023, 16100-ZM0-803, 16100-Z0L-023

What It Is

This is a replacement carburetor for Honda GCV160 engines—the small vertical-shaft power plants found on many Honda lawn mowers, pressure washers, and tillers. It meters fuel and air into the cylinder for combustion and is the typical fix for hard-starting, surging, or stalling engines.

Fitment & Compatibility

Before buying, confirm your engine model number—not just the mower brand. This carb fits Honda GCV160A, GCV160LA, GCV160LAO, and GCV160L E engines. It directly replaces OEM part numbers 16100-Z0L-023, 16100-ZM0-803, and 116100-Z0L-023. It also works on Honda mower models HRB216 and HRS216 that use those engines.

Check three things:

1. Engine model – Look on the engine shroud for a sticker (e.g., “GCV160LA”).
2. Gasket pattern – Verify the intake flange matches your old carb’s bolt spacing (two bolts, roughly 2.5 inches apart).
3. Choke linkage – This carb uses a manual choke lever; if your engine has an auto choke, this won’t work.

Key Things to Know

• Quality concerns – At $13.59 with a 3.4-star rating from only 3 reviews, this is a budget aftermarket part. Expect potential fitment issues like slightly misaligned bolt holes or soft gaskets. Many users report needing to swap the old gasket or jets.
• Installation difficulty – Moderate. You’ll need to remove the air filter housing, fuel line, and two bolts. Clean the intake manifold surface thoroughly. Expect to adjust the idle mixture screw (turn gently until it seats, then back out 1.5 turns).
• Common gotchas – The included gaskets may leak; reuse your original Honda gasket if possible. Also, the fuel inlet barb can be slightly smaller than OEM, requiring a tight hose clamp. After installation, prime the carb by pouring a teaspoon of gas into the throat.
• No warranty – Most sellers of this price point don’t offer returns on fuel parts, so you’re buying as-is.

Should You Buy It

Buy this if your GCV160 engine won’t start or runs poorly, and you want a quick, cheap fix—especially if you’re comfortable with basic carburetor work and can swap gaskets or jets. Skip it if you need a guaranteed fit for a commercial mower or if you’d rather pay double for an OEM Honda carb that bolts on with zero adjustment.
