Chainsaw Pull Start Repair

Chain saw pull start rope breaks happen, but they’re relatively easy to replace.
Generally all you’ll need is a screwdriver, although pliers and a wrench can come in handy as well. Once you get the hang of it, a pull start rope replacement should take less than 10 minutes.

Start by removing the side cover over the starter. You’ll find the old pull start rope connected to the starter assembly under the side cover.

If you can see the knot in the starter assembly, carefully  pull it outwards until you can untie the knot. Then remove and replace the old pull start rope.

If you can’t see the rope’s knot you may need to open up the chainsaw’s starter assembly. Generally starter assemblies are held together by one screw in their center. Undo the screw to remove the cover and have a look inside.

If you’re able to, untie and remove and replace the old pull start rope without removing the spool.

If you must remove the spool, or if you’d like to remove the spool to replace it or check for signs of damage, then do so but pay special attention to the spring and its positioning. Make sure the spring meshes under the pulley when you replace it. You may need to wind the pulley approximately four rotations in order for it to pull the rope into the starter. If there isn’t enough tension your chain saw won’t start no matter how many times you pull the rope.

Complete pull start / recoil assemblies are available for as low as $15. These are ready to install units complete with new plastic housings that remove the need to disassemble the original part. These bolt on chain saw parts and are often purchased to save time and frustration.

To insert a new starter pull rope align the hole in the side of the pulley with the hole in the side cover casing. Thread your rope through the side cover and into the pulley, and then tie a knot at the end of it.

You might want to clean up any dirt or debris while your chainsaw is apart.

If you previously had to open up your starter assembly, reseal it now.

Now you can slowly let the pull rope recoil back into the starter. If your chain saw has a pull rope handle, run the rope through the handle and knot it. Replace the side cover, start your chain saw up, and get back to chopping!
