Recoil spring very old model

Stripped? Maybe the recoil Spring just broke. Easy repair, sometimes you can just re-bend the 'Stop' on the old Spring

I have the same chainsaw and have never had a problem with it.

If you have changed the starter rope or recoil spring in the past, it is important that you hold the new spring with needle nose pliers and install it correctly. Once the spring is in make sure wind the rope correctly-clockwise. If not the new spring will be damaged.

While I have not done this on newer model lawn mowers, I have replaced recoil springs in the past. Here's what I did: First you need to pull the spark plug wire off so the engine will not start. Then block the flywheel with a piece of wood to keep it from turning. Then, using another piece of wood such as a short (6-8 inch) hardwood dowel placed against the ears of the recoil drive, and drive it in a reverse direction (clockwise) with a hammer to knock it loose. It may take several sharp blows to break it loose. The recoil drive is reverse threaded to keep it from coming loose when the engine is running. Once the drive is loose, remove it to get access to the recoil spring which must be replaced if it is broken. With a new spring in place, rethread the recoil drive counter clockwise until it is finger tight. Then, tighten it down with one sharp blow against the wooden dowel.

You need to remove the Recoil

Remove the Old line

Insert the new line

Wind the spring tight

Ensure you have 6 feet outside

SO YOU UNDERSTAND. THE SPRING IS COMPLETELY WOUND (Then backed off ONE ROTATION). and then allow the spring to RECOIL to PULL the line in and then the Pull Length. it will become quite clear as you are doing it

If you are having to recoil the spring after its come out. Roll it tightly with your hands then use vise grips on one side pinching it together then you can place it in the retainer/pulley. release

You need to pretension it. Remove the pull handle, rotate the spool about 2 revolutions against the spring, rethread the cord and reinstall the handle.

Order a new recoil spring from your suppier. It comes wound up. Remove the old part first usually four screws on the outside. Make sure the rope is fully wound then insert the new spring and reassamble. If it becomes unwound by mistake its a labourious job to rewind but can be done.

try your local mower shop tell what type it is the modle number and make the should be able to cross refrenesss it and get the right one

My UT21546 has 2 springs, the regular recoil one and a what I'll call a anti kickback one. the top of the anti kickback spring kept coming unsecured and finally I just deleated it alltogther and screwed the 2 plates tightly togehter and the near new unit works better than new now.

you need to supply the brand and model of the blower so i can look it up
