YAMAKATO GX340 GX390 Recoil Starter Pull Start Assembly w/Pull Cord for Honda GX610 GX620 and Clones 339c 389cc 420cc 439cc 459cc Red 28400-ZE3-W01ZA for Pressure Washers Generators etc.

What It Is

This is an aftermarket recoil starter assembly designed to replace the pull-start mechanism on Honda GX610 and GX620 engines, plus their clones in the 339cc–459cc range. Commonly used on pressure washers, generators, and other small-engine equipment.

Fitment & Compatibility

Before buying, confirm your engine’s displacement and bolt pattern. This assembly fits:

• Honda: GX610, GX620, GX340, GX390 (and clone equivalents)
• Displacement: 339cc, 389cc, 420cc, 439cc, 459cc
• OEM Reference: 28400-ZE3-W01ZA
• Measurements: Typical center-to-center bolt spacing is 3.125” (79.4mm). Measure your old starter’s mounting bolt holes to verify.
• Not compatible with smaller Honda engines (e.g., GX160, GX200) or non-clone brands without adapter plates.

Key Things to Know

• Quality vs OEM: Aftermarket; decent for the price but may have slightly thinner plastic housing or less durable pawls than genuine Honda. Expect 2–3 seasons under heavy use.
• Installation difficulty: Easy—remove two bolts, swap the starter, reconnect the cord. No special tools needed.
• Common gotcha: The pull cord length (approx. 60”) may be shorter than OEM; if your engine has a large flywheel or tight routing, the cord may not fully retract. Test before reassembling.
• Cord replacement: The included cord is replaceable, but the spring is pre-wound. If the spring snaps, you’ll need a new assembly—repairing the spring is not practical.

Should You Buy It

Buy this if you need a quick, budget-friendly replacement for a worn or broken recoil starter on a Honda GX610/620 clone engine (pressure washer, generator, or industrial equipment). It’s not for high-hour commercial use—if you run your machine daily, spend more on a genuine Honda unit for better durability. For occasional home or job-site use, this is a solid value.
