YAMAKATO GCV160 Throttle Return Spring Linkage With Carburetor Gasketet Set Kit for Honda Toro Cub Cadet Craftsman Lawn Boy HRR216 HRB216 HRX217 Carburetor Governor Spring Link Rod Speed Control

What It Is

This is a replacement throttle return spring and linkage assembly, paired with a carburetor gasket set, designed for Honda GCV160 engines used on Toro, Cub Cadet, Craftsman, and Lawn Boy mowers (models HRR216, HRB216, HRX217). It restores correct throttle response and governor control when the original spring breaks or linkage wears out.

Fitment & Compatibility

• Engine requirement: Only for Honda GCV160 engines. Check your engine’s model number (e.g., GCV160A) stamped on the valve cover or blower housing.
• Mower models: Fits Honda HRR216, HRB216, HRX217, plus Toro, Cub Cadet, Craftsman, and Lawn Boy mowers using the GCV160 engine. Not for larger GCV190/200 or older GXV engines.
• OEM vs aftermarket: This is a non-OEM kit. It includes the spring, linkage rod, and carburetor gaskets. OEM part numbers for reference: 16211-ZL8-003 (spring) and 16010-Z0H-801 (gasket set). Compare shape and length of the linkage rod to your original—aftermarket rods may require slight bending.
• Measurements: The spring is about 1.5 inches long; linkage rod is roughly 4.5 inches. If your existing rod is a different length, you may need to modify or buy an OEM part.

Key Things to Know

• Installation difficulty: Easy for DIYers with basic tools (screwdriver, needle-nose pliers). Takes 15–30 minutes.
• Common gotcha: The throttle return spring must hook onto the correct tab on the carburetor lever and the fixed bracket. If it’s misrouted, the engine will race or stall.
• Gasket quality: The included carburetor gaskets are thin paper—they work fine but may tear if over-tightened. Use a light touch when reinstalling the carburetor.
• Durability: Aftermarket springs are similar to OEM but may rust faster. Keep the area clean and dry.

Should You Buy It

Yes, if your Honda GCV160-powered mower has weak throttle response, a broken spring, or you’re rebuilding the carburetor. At $8.99, it’s a cheap fix for a common failure—just verify engine model and rod length before buying.
