I have a Hitachi CG22EASSLP string cutter. Light weight , was running good, great for reaching down the bank of the pond. Last year it was giving me problems starting and stay running. Decided to give it a rest and bought a battery trimmer. Battery trimmer works great but I find it is a little under powered for cutting around the pond. Decided to work on the Hitachi. I found bad fuel lines. Changed out all 3 with generic fuel lines from ebay and now this thing runs like new. Funny how the very simple things is all that it needed.
