How do you fix a pullstring on a lawnmower?

A pullstring on a lawnmower is pretty easy to fix. Most models have a few bolts around the cover of the pullstart. Some models will have a plastic cover on or around the pullstart cover, it will need to be removed first. Some models will also have a bolt holding the oil and/or gas spout onto the side of one of the covers. Once you have the pullstart cover off [DO NOT TAKE THE SPRING UNIT INSIDE THE COVER APART.] you will need to remove the broken piece of rope. There is usually a knot at the end of the rope. If the knotted piece of rope left is about three inches or less, you will be able to remove it using a pair of needle nose pliers. Just grab the knot and give it a good pull. If the break is longer than three inches you may need to buy a replacement pullcord. They are about 5-10 dollars at most hardware stores.

Now to put it back together, you will need to re-wind the spring first. Before you do though, it helps to have a second set of hands ready to help you. Wind the spool up until it is firm but its important not to force it or te spring may break. If the spool stops spinning it is too tight.Youwill need to let a little tension off the spring.after winding the spring. you will need to have your helper hold the wound up spring while you re-thread the rope through the cover and then through the spool. You will need to have the two holes lined up to push the rope through far enough. then make a knot in the rope end and slowly let the rope re-spool itself. If the spring is wound enough the whole rope should pullinto the spool right up to the pull-handle. Then just put the covers back on and you are ready to go.
