In this video, we learn how to fix a slack chainsaw recoil starter. All you need is to wind up the recoil string so the tension can be put back on. First, remove the bolts out (there will be around four of them). Next, lift the side casing off and find the nylon spool with the cable cord wrapped around it. There will be a clock spring around that. Now, wind it up with a screwdriver while holding the spool of the corn and winding up the spoon a couple of times. When you reach the correct tension, replace all the parts that you just took off and you are finished!
