Quick answer
A broken pull cord is usually a snapped or frayed rope, not an engine problem. Pull the spark plug wire off first, unbolt the recoil starter cover and thread a new rope of the right thickness through the housing and onto the pulley, with the spring wound a few turns. A starter rope kit costs little and the job takes under an hour. If the rope is fine but will not pull out or retract, the cause is a stuck pulley or a weak or broken spring.
Free fix vs. permanent fix
Re-knot the old rope
- Pull the spark plug wire off the plug
- Cut off the frayed end of the rope
- Tie a stopper knot at the handle end
- Melt the cut end with a lighter so it does not fray
How long it lasts: Only until the rope frays again, which is often within a few pulls if age caused the fraying. It only works if enough rope is left.
A replacement recoil starter rope kit
Starter rope wears from rubbing through the housing eyelet and from being pulled at an angle. Old rope frays and snaps again. A new rope of the right thickness, sized for your engine, restores the whole pull.
What to get: Lawn mower recoil starter rope kit
How long it lasts: Years. Fresh rope and a new handle replace the part that wears out.

Why it happens
Age and sun wear
Starter rope is braided nylon or polyester. It weakens with sun, heat and fuel splashes over the years.
Pulling at an angle
Yanking the handle sideways rubs the rope against the housing eyelet and wears it through.
A stuck pulley or a hard-to-turn engine
Debris or rust in the housing, a flooded engine or an engaged blade brake makes pulls hard and can fray the rope.
Spring failure
The recoil spring can break or lose tension, so the rope stops retracting even when the rope is fine.

Do these in order, starting with the simplest.
-
Disconnect the spark plug
Tool used: Safety glasses and glovesPull the rubber boot off the spark plug and tuck it aside, so the engine cannot fire while you work. Put on safety glasses and gloves.
-
Remove the starter cover
Tool used: Socket set or wrenchTake a photo of how it sits, then unbolt the recoil housing from the top of the engine. Lift it off and keep the pulley from spinning.
-
Take out the old rope
Tool used: Needle-nose pliersPull the old knots and rope pieces out of the pulley and the handle. Note how the rope runs and where it knots.
-
Cut and seal the new rope
Tool used: LighterMatch the thickness to your old rope or the manual. Cut it to the length given in the kit, and melt both ends with a lighter so they do not fray.
-
Thread the rope and set the spring
Tool used: Replacement recoil starter rope kitFeed the rope through the housing eyelet and the handle, and knot both ends. Wind the pulley a few turns against the spring, as shown in your manual, hold it and let the rope retract slowly.

Refit and test
Bolt the housing back on and pull the rope slowly to check it extends and retracts fully. Refit the spark plug boot and start the mower.
When free fixes aren't enough
If the rope is whole but hangs limp and will not retract, the spring has lost tension or popped out. Wind the pulley a turn or two more first. If the spring is broken or the pulley is cracked, a complete recoil starter assembly is a simple bolt-on swap. If the rope will not pull at all, do not force it. A hard pull usually means the engine is locked, flooded or the blade brake is engaged, and an engine that will not turn needs a shop.

Lawn mower recoil starter rope kit
Fixes: a snapped or frayed starter rope
Look for: Rope thickness and length listed for your engine; A new handle included; Braided rope that resists fraying; A fit list or a diagram that matches your manual.
- Who it's for
- Anyone whose pull cord has broken or worn and whose mower otherwise runs.
- Honest downside
- Your mower is battery powered or electric start only. There is no rope. Also skip it if the spring or pulley is broken, since you need the assembly.

- Who it's for
- Anyone who can reuse the handle and wants the cheapest fix.
- Honest downside
- You are unsure of the right rope size. A kit lists it for you.

- Who it's for

How we picked: How we picked: this page is based on mower owner manuals, small-engine repair guides, and what owners report in reviews of starter rope kits. We do not test products by hand.
Stay safe: the spring is under tension
- Pull the spark plug wire before you start, and keep the plug wire away from the plug.
- Wear safety glasses. A recoil spring can snap out of its housing.
- Keep fingers out of the pulley and never let go of it while it is wound.
- If the mower leaks gas or oil, tip it the way your manual says, with the carburetor side up.
What to skip
Clothesline and general-purpose twine
Soft, slick cord is not made for a starter pulley and frays or stretches after a few pulls. Use rope made for starters, and do not rewind a recoil spring by hand when it has broken.
