16100-Z0L-853 Carburetor for Honda GCV160 GCV160A GCV160LA GCV160LA0 S3A NH1 5.5hp 160cc Engine Lawn Mower Manual Choke Carb

What It Is

This is a complete, ready-to-install carburetor assembly for Honda GCV160 engines (160cc, 5.5hp) with a manual choke. It replaces OEM part 16100-Z0L-853 and is used on push mowers, pressure washers, and other small equipment powered by that engine family.

Fitment & Compatibility

Check these before buying:

• Engine model: Must be Honda GCV160, GCV160A, GCV160LA, or GCV160LA0 S3A NH1. Look for the engine model number stamped on the blower housing or valve cover.
• Choke type: This is a manual choke carb. If your engine has an auto choke (electric or thermowax), this won’t work.
• OEM vs aftermarket: This is a genuine Honda part, not a cheap clone. It should bolt directly on without modifications.
• Gasket/fuel line fit: Confirm your mower uses the standard round bowl gasket and 1/4” fuel line. Most Honda GCV160 applications do, but double-check if you have an oddball model.
• Deck size irrelevant: Carb fitment depends only on the engine, not the mower deck size or brand.

Key Things to Know

• Ease of install: Moderate difficulty. Expect 30–60 minutes if you’ve done small engine work. You’ll need a socket set, screwdriver, and possibly a carburetor gasket set (not included).
• Adjustment needed: The idle mixture screw is pre-set from Honda, but you may need to tweak it after install if the engine runs rough or stalls.
• Common gotcha: The choke linkage can be tricky to align. Take a photo of the old carb’s linkage before removal to avoid confusion.
• Quality: Genuine Honda means reliable construction and correct float height. Avoid cheap knockoffs that often leak or fail within weeks.

Should You Buy It

Buy this if you need a direct, reliable replacement for a worn-out or clogged manual choke GCV160 carburetor and want OEM quality without paying dealer markup. It’s a solid choice for DIYers comfortable with basic engine work. If you have an auto-choke engine or want to save money with a $10 aftermarket carb, skip it.
