GCV160 Carburetor for Honda 16100-Z8B-901 GCV160LA0 S3B GCV160LA1 S3B Engine HRR216K9 K10 K11 HRS216K5 K6 K7 Mower GCV 160 Carburetor for Husqvarna HU700F HU700H 7021P Lawn Mower-Auto Choke

What It Is

This is an aftermarket carburetor assembly for Honda GCV160 engines (16100-Z8B-901) with auto choke, designed to replace the factory carb on Honda HRR216, HRS216 mowers and select Husqvarna HU700F/HU700H/7021P models. It controls the fuel-air mixture for starting and running the engine.

Fitment & Compatibility

Before buying, verify your engine’s model number (stamped on the engine shroud, not the mower deck). This carb fits:

• Honda GCV160 engines: GCV160LA0 S3B, GCV160LA1 S3B
• Honda mowers: HRR216K9, K10, K11; HRS216K5, K6, K7
• Husqvarna mowers: HU700F, HU700H, 7021P

Critical checks:

• Measure your existing carb’s mounting bolt spacing (center-to-center). This unit uses two M6 bolts ~50mm apart.
• Ensure your engine has an auto choke (electric solenoid on the choke plate). Manual choke engines use a different carb.
• OEM part number 16100-Z8B-901 is the direct reference. Aftermarket versions may vary slightly in gasket thickness or jetting.

Key Things to Know

• Quality variance: At $16.99, this is a budget aftermarket part. Some units may need jet cleaning or adjustment out of the box. Expect 60-70% of OEM reliability.
• Installation difficulty: Moderate (30-45 minutes). Requires removing the air filter housing, fuel line, and throttle linkage. Have a small screwdriver set and a 10mm socket ready.
• Auto choke wiring: The electric choke must connect to the mower’s harness (usually a spade terminal). No connection = no choke operation, hard starting.
• Common gotchas: The included gaskets may be too thin. Reuse the OEM gasket or add a thin layer of sealant. Also, the fuel inlet barb may be slightly smaller than stock—check your fuel hose inner diameter (5/16” typical).

Should You Buy It

Buy this if you need a cheap, quick fix for a non-starting GCV160 mower and want to avoid a $60+ OEM carb. It’s fine for occasional home use or as a spare. Skip it if you rely on your mower commercially, want long-term durability, or have a manual choke engine—go OEM for those cases.
