YAMAKATO Recoil Starter Spring for Honda gx120 gx140 gx160 gx200 28442-ZH8-003 Pull Strat Spring 5hp 5.5hp 6hp 6.5hp 163cc 196cc

What It Is

This recoil starter spring is the coiled tension spring inside the pull-start assembly that retracts the starter rope after each pull. It’s designed for Honda GX120, GX140, GX160, and GX200 engines (5–6.5 hp, 163–196 cc), commonly found on walk-behind mowers, pressure washers, generators, and small tillers.

Fitment & Compatibility

• Direct OEM replacement for Honda part number 28442-ZH8-003.
• Fits engines with a vertical or horizontal shaft that use the standard Honda recoil housing.
• Check your engine model (stamped on the blower housing or valve cover) – only GX120/140/160/200, not GX100, GX240, or GX270.
• Measure the spring’s inner diameter (approx. 1.5 inches) and coil count (typically 6–7 turns) before buying; aftermarket springs can vary slightly.
• If your recoil housing is cracked or the pulley is worn, you’ll need those parts too – this is just the spring.

Key Things to Know

• Installation is tricky – the spring is under tension. Wear safety glasses and use a zip tie or clamp to hold it coiled before inserting into the housing.
• Quality vs OEM: Yamakato is a solid aftermarket brand; most users report it works as well as the Honda original, but a few note slightly thinner wire.
• Common gotcha: If the spring is installed backwards or the hook end doesn’t seat fully in the pulley slot, the rope won’t retract. Watch a 2-minute video guide before starting.
• No other tools needed beyond a screwdriver and pliers – but patience is required.

Should You Buy It

Yes, if your Honda GX120–200 engine’s pull starter is sluggish, won’t retract, or the rope is loose. At $7, this is a cheap fix that avoids replacing the entire recoil assembly. It’s best for DIYers comfortable with small engine repairs; if you’ve never worked on a recoil starter, budget an extra 20 minutes for the learning curve.
