I had just recently purchased the tornado xl. ive only had it for about 4 days and, when i went to go start it up again in the morning the string came all the way out and never went back in, and i didnt even pull it that hard, i barely pulled it, the cord didnt snap or anything it just came out and didnt retract back in. i am very furious because first my clutch shoe spring broke about 3 times and now my pull string!!!!!!!!!i dont know what else to do,
