Craftsman weedwhacker string help.
The knot to my pull string pull came out and the string spooled itself around the spool. No problem, right? I took it apart and restrung it around the spool, retied the knot and put it back together. But, I guess there must need some kind of resistance b/c when I pull the string itÂs taut and will not turn on the motor. What do I need to do?
