ALL-CARB GCV160 Carburetor Replacement for Honda GCV135 GCV160 GC135 GC160 Lawn Mower Replace 16100-Z0L-023 16100-ZM0-804

What It Is

This is a complete aftermarket carburetor replacement for Honda GCV135, GCV160, GC135, and GC160 engines. It’s designed for walk-behind mowers, pressure washers, and small power equipment using those engines.

Fitment & Compatibility

• Engines: Honda GCV135, GCV160, GC135, GC160 (check your engine model number, not just the mower brand).
• OEM Part Numbers: Replaces 16100-Z0L-023 and 16100-ZM0-804. Confirm your original carburetor ends in these numbers.
• Deck size: Irrelevant; only engine model and carburetor part number matter.
• Aftermarket note: This is not a genuine Honda part. It may have slight differences in gasket thickness or jet tuning. Verify the mounting bolt pattern matches your engine block.
• Check: Remove your old carburetor and compare the gasket shape, fuel line fitting size, and throttle linkage layout before installing.

Key Things to Know

• Quality: Budget aftermarket carb. Works for many, but some report needing to clean out debris or adjust float height out of the box.
• Installation difficulty: Moderate. You’ll need to replace gaskets, reconnect fuel lines, and adjust the idle mixture screw. Expect 20–40 minutes.
• Common gotcha: The choke linkage may not align perfectly with your mower’s control cable. You may need to bend or adjust the linkage slightly.
• Tuning: The pre-set idle mixture is often lean. After installation, turn the mixture screw 1.5 turns out from fully seated as a starting point, then fine-tune.

Should You Buy It

This is a good budget fix if your original carburetor is clogged or damaged and you’re comfortable with minor adjustments. It’s not ideal if you need a perfect drop-in replacement with zero tinkering, or if your engine has a complex governor linkage that requires precise fit. For the price, it’s worth trying before spending on an OEM Honda carb ($40–60).
