After reading the great reviews on the Echo 261t, I decided to purchase one. However, it's been a big disappointment. The engine sounds like it's muffled and not running smoothly. It makes a lot of noise but doesn't cut anything. At 25.4 cc, it actually has less power and strength than my 22.5 cc Shindaiwa t230 trimmer. I took it back to the dealer, he did some adjustments and said the trimmer needs about 20 hours to break in. He also said that Echo units in general, don't have the same power as other brands like Stihl, Shindaiwa etc. Is it normal for this trimmer to be doing this or something wrong?
