What It Is

This is a complete aftermarket manual choke carburetor designed to replace the OEM carb on Honda GC160, GCV160, and related engines. It’s intended for lawn mowers (HRR216, HRS216, HRT216, HRZ216) and pressure washers using those engines.

Fitment & Compatibility

• Engine families: Honda GC160, GCV160, GCV160A, GCV160LA – check your engine’s model code (stamped on the valve cover or shroud).
• Mower models: HRR216, HRS216, HRT216, HRZ216 series – verify your specific deck size (e.g., 21-inch) and year; older models may have minor differences.
• OEM part numbers replaced: 16100-Z0L-003, 16100-Z0L-023, 16100-ZM0-023 – cross-check your old carb’s number.
• Measurement check: Ensure the mounting flange bolt spacing matches (typically 60mm center-to-center) and the choke lever orientation aligns with your throttle cable setup. Measure the old carb’s intake bore diameter (usually 18mm) – this unit matches that.
• Brand note: This is an aftermarket part, not genuine Honda. It may use different gaskets or fuel line fittings – compare the included gasket to your old one.

Key Things to Know

• Quality: Budget aftermarket carb – works well for most users, but some report needing to clean out machining debris or adjust the float height out of the box.
• Installation difficulty: Moderate – requires removing the air filter housing, fuel line, and throttle linkage. Have a small screwdriver set and a 10mm socket handy.
• Common gotcha: The manual choke lever may be stiff initially; lubricate with WD-40 if needed. Also, the included fuel line may be slightly too short or stiff – reuse your original line if possible.
• Tuning: You may need to adjust the idle mixture screw (turn 1.5 turns out from fully closed as a starting point) and check for vacuum leaks around the gasket.

Should You Buy It

Buy this if you have a Honda GC160/GCV160 engine with a manual choke, need a budget fix for a clogged or failing carb, and are comfortable with minor adjustments. Skip it if you want a plug-and-play OEM replacement or have an auto-choke model – those require a different carb.
