Curb picked an echo SRM-2100. Only thing keeping it from running was the primer bulb. New bulb and fired right up. Only a couple of issues with it but nothing major. Tank vent leaks. The head isn't quite right. Had to add a washer to space out the line advance mechanism so that it would let line out. The throttle cable sticks so you have to push the trigger back down by hand. I think I like it more that my Stihl FS55R.
