Hello all. I have an echo hc 152 a bought two years ago. Now I maybe use it for a couple hours total a year. A month ago I fired it and my echo grass trimmer up to just run them. Grass trimmer worked fine but hedge trimmer won't take throttle. Bogs down. Now with my low use of this equipment I realised the gas in it was still the stuff the dealer put in it when I bought it. Two years ago..... Oops. I know better than that but must have slipped my mind. So I drain the old fuel and put in some husky premix figuring the little use it gets would be a good fuel. Still won't run. I rebuilt the carb with a factory kit and changed fuel filter. Still will not run. Found online about the hidden fixed jet. Yay now I'll get it. I removed the jet, cleaned it with wire and carb cleaner.... Still won't run. Also now the primer bulb won't fill up. The only thing I haven't changed is the spark plug but it looks just fine. The machine is still under warrantee but I'm sure this will not be covered. Air filter is also fine. Any ideas? It definitely feels like a lean issue but I can't seem to fix it. Idles rough but will idle but when I open the throttle it will not rev.
