I got the 2 stroke straight shaft 25cc feather light weed eater brand line trimmer, i have only used it a couple of times but it works gread, the only con is when you use the auto feed you have to be running it wide open or it will die needs more umph! to cut the line.Other than that it really gets the job done especially like how easy it is to start right out of the box.In the instructions it tells you to hold the throttle wide open when starting, not true if the engine is already warmed up, do not prime or touch the throttle, once it is warmed up it will fire in one pull!
