What It Is

This is a replacement carburetor for Honda GCV160 engines, commonly used on Honda HRT216, HRB216, HRZ216, HRR216, and HRS216 walk-behind mowers. It meters fuel and air into the engine for combustion.

Fitment & Compatibility

• Engine models: GCV160, GCV160LA, GCV160A, GCV160LA0. Check your engine’s model number (stamped on the blower housing or valve cover).
• Mower models: HRT216, HRB216, HRZ216, HRR216, HRS216. Verify your mower’s model tag under the seat or on the frame.
• OEM part numbers: Replaces 16100-Z0L-023 and 16100-Z0L-853. Compare your old carb’s number; aftermarket may differ slightly in jetting or gasket fit.
• Deck size: Not relevant—fitment is engine-dependent, not deck size.
• Measurements: Intake flange and mounting bolt pattern match OEM. Confirm throttle/choke linkage style matches your engine (some have plastic vs. metal linkage arms).

Key Things to Know

• Quality: Aftermarket carb; may need minor adjustment (idle speed screw) and cleaning of debris from shipping. Not as durable as OEM but functional for most users.
• Installation difficulty: Moderate. Expect to remove the air filter housing, fuel line, and two bolts. Have a small screwdriver and pliers handy. Watch for gasket alignment—reuse old gaskets if the new ones don’t seal perfectly.
• Common gotchas: The included gaskets may be thin or misaligned—test fit before tightening. Fuel line may be stiff; warm it or use a small clamp. If engine runs rich/lean, clean the new carb’s jets (they sometimes have machining debris).
• Primer bulb: This carb includes a primer bulb; ensure your engine uses one (not all GCV160 variants do).

Should You Buy It

If your Honda GCV160-powered mower has carburetor issues (hard starting, stalling, flooding) and you want a low-cost fix without OEM markup, this is a solid stopgap. It’s right for DIYers comfortable with basic engine work. For commercial use or long-term reliability, stick with an OEM Honda carb.
