I have a sears anniversary edition weedeater.the trimmer ran good for about two years,then it started giving me problems.i thought that maybe it was an ignition problem.what i did was disconnect the on and off switch and used a jumper. it ran for about 30 seconds then quit. did i possibly burn up some electronic component,what can i do to fix it,what do i need to replace. thanks.
