GCV160 Carburetor for Honda GCV160LA0 GCV160LA0G5B GCV160LA1 GCV160LA1N5BR Engine, Replace# 16100-Z8B-911, Manual Choke Carb with Air Filter Kits

What It Is

This is a complete carburetor assembly with manual choke and air filter kit, designed to replace the OEM Honda 16100-Z8B-911 on Honda GCV160 engines used in walk-behind mowers, pressure washers, and small utility machines.

Fitment & Compatibility

Check your engine model number – this fits Honda GCV160LA0, LA0G5B, LA1, and LA1N5BR engines. Not all GCV160 variants use the same carburetor (some have auto choke or different mounting). Verify your engine’s code tag (stamped on the blower housing) matches one of the listed models. Also confirm you have a manual choke – if your original carb has a primer bulb, this won’t work. The air filter kit is included but check that the filter housing and gasket match your current setup; some GCV160s use a different filter base.

Key Things to Know

• Quality vs OEM – This is an aftermarket replacement, not Honda OEM. It typically works well out of the box, but some users report needing to adjust the idle mixture screw or clean out machining debris before install.
• Installation difficulty – Moderate. You’ll need a socket set, screwdriver, and possibly a small pick for old gasket removal. Expect 30–60 minutes if you’re handy.
• Common gotcha – The included gaskets may be slightly thicker than OEM. Check that the bowl nut is snug (not overtightened) to avoid leaks. Also, the manual choke lever orientation might need a small adjustment to align with your mower’s cable.
• Fuel system prep – Old fuel or debris in the tank can clog the new carb. Drain and clean the tank, and replace the fuel filter if your mower has one.

Should You Buy It

If you have a confirmed GCV160LA0/LA1 engine with manual choke and your original carb is worn or clogged, this is a solid budget fix. It’s not Honda quality, but for $26 it’s a practical choice for DIYers who want a direct replacement without rebuilding the old unit. Skip it if you need exact OEM fit for a pressure washer or commercial use.
