Chosen Solution

I have changed out on echo srm 225 weed eater spark plug, fuel, air filter, fuel filter it will start with full choke but soon you start to turn choke down will stall out and also will not idle up when giving it throttle up speed does not change

@rebel1,David, A couple things to check for,Good/fresh fuel proper mix, loosen gas cap and see if engine runs better, if runs OK the vent in the fuel cap is clogged. When fuel filter was change did it fall back to correct position(laying at bottom of tank) or did it get hung up staying upper level of tank(not fully submerged in fuel). Remove spark arrester from muffler and clean(when clogged the engine will perform in this manner) link below show method, If still no go possible dirt in carburetor/weak diaphragm/hole in fuel line or pinched. Good luck. I hope this helped you out, if so let me know by pressing the helpful button. https://www.youtube.com/watch?v=U0LJ3gX2
