GCV160 Throttle Return Spring Linkage Kit for Honda GCV190 GSV190 Toro Cub Cadet Craftsman Lawn Mower HRR216 HRB216 HRS216 HRT216 HRZ216 HRX217 Carburetor Governor Spring Link Rod Speed Control

What It Is

This is a throttle return spring linkage kit designed to restore proper governor and speed control function on Honda GCV160, GCV190, GSV190 engines, commonly used in Toro, Cub Cadet, Craftsman, and other walk-behind mowers (HRR216, HRB216, HRS216, HRT216, HRZ216, HRX217). It replaces worn or broken springs and linkage rods that cause surging, stalling, or uncontrolled engine speed.

Fitment & Compatibility

Before buying, confirm your engine model (look on the valve cover or engine shroud—GCV160, GCV190, or GSV190). This kit is aftermarket, so check that your mower uses a side-mounted carburetor with a throttle cable and governor arm. It fits most Honda GCV/GSV-powered mowers from Toro, Cub Cadet, Craftsman, and others, but does not fit overhead-valve (OHV) engines like GXV or GC. Measure the existing spring length and rod diameter to match (kit includes common sizes). If your mower has a different linkage setup (e.g., a different governor arm or plastic carburetor cover), this kit may not work.

Key Things to Know

• Quality is acceptable for the price – springs are slightly thinner than OEM but function fine for residential use. Don’t expect Honda-grade durability.
• Installation is moderate – you’ll need needle-nose pliers and patience to hook small springs without bending them. A service manual or YouTube video helps.
• Common gotcha – the linkage rod must be properly seated in the governor arm and carburetor throttle plate hole. If it’s too loose or too tight, engine speed will be erratic.
• Check for missing parts – some kits come with extra springs you may not need; compare to your original setup before discarding anything.

Should You Buy It

If your Honda GCV/GSV-powered mower is surging, won’t idle, or has a broken/lost throttle spring, this kit is a cheap, effective fix for DIYers. It’s not built for commercial use, but for a $9 repair that saves a trip to the dealer, it’s a solid choice for most homeowners.
