What It Is

This is an aftermarket auto choke carburetor designed to replace the OEM unit on Honda GCV160 engines. It’s used in lawn mowers (HRT216, HRB216, HRR216, HRS216, HRZ216) and pressure washers—any machine powered by a Honda GCV160, CV160, or GCV160A0/LA/LE engine.

Fitment & Compatibility

Engine models: Honda GCV160A0, GCV160LA, GCV160LA0, GCV160A, GCV160LE, CV160A0.
Machine series: HRT216, HRB216, HRR216, HRS216, HRZ216 (and compatible pressure washers).
OEM part numbers: 16100-Z1L-854, 16100-Z0L-023.
What to check before buying:

• Confirm your engine’s exact model number (stamped on the engine shroud or valve cover).
• Measure the mounting flange bolt spacing (standard for GCV160, but verify).
• Ensure your throttle/choke linkage style matches—auto choke versions have a specific vacuum-actuated choke that differs from manual choke models.
• This is an aftermarket part, not OEM Honda; fitment is generally good, but minor adjustments (e.g., gasket thickness) may be needed.

Key Things to Know

• Quality: Aftermarket; typically works well but may have slightly less precise machining than OEM. Clean out any debris before installation.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, disconnect fuel and throttle linkages, and swap the carb base gasket. Watch for small springs and clips.
• Auto choke tuning: The auto choke is vacuum-operated; if the engine floods or won’t start, check the choke plate moves freely and the vacuum line is intact.
• Common gotchas: The included gaskets may be thin; reuse your OEM gasket if possible. Fuel line size is standard 1/4″; verify your existing hose fits. Some users report needing to adjust the idle mixture screw (if adjustable) for smooth idle.

Should You Buy It

Buy this if you have a Honda GCV160 engine with a failing auto choke carburetor and want an affordable replacement that’s easy to install with basic tools. It’s a solid value for DIYers who don’t need OEM pedigree and can handle minor tweaks. Skip it if you prefer exact OEM fitment or your engine has a manual choke—this carb is auto choke only.
