I have pulled the cord out of my gas powered trimmer. What is the easiest way to fix this
ANSWER : Remove the pull start mechanism, remove the old rope from the inside plastic, thread a new rope through the hole in the outside and through the hole in the plastic center where you removed the old rope, Now reach between the spool and the edge of the casing and pull some slack in the rope, there will be a notch in the spool, set the rope into the notch and begin spinning the spool to make tension in the spring ( correct direction is the same way the rope is spooled in. go until you have good tension on spring, grab rope left outside casing and pull through, then let rope get pulled into the spool with the spring tension you have created. Now just reattach the handle.
