I am having the weirdest issue with my echo weed eater. First of all, if i lay it down flat on the garage floor, all the fuel leaks out ovenight. I am assuming the tank has a leak but the trimmer is a year old and you can't really tell where the leak is coming from. Second, when i do get it running, it will run perfect for about 10 seconds and then begins to sputter and then eventually dies. I have used brand new gas mixture and checks every issue the manual has suggested. Please help me, so far this year has been trying to say the least and i am trying to save shop repair costs. Thanks.
