Weed Eater One

Ok here we go I have an elderly neighbor that purchased a Weedeator One said that was all she could afford. The problam she was cutting to close to the curb and didn't realize the front left tire was flat and it rolled over into the street(she is ok just scrapes and bruises) I guess it is out of warrenty if in fact she even registered it? I can get the mower to start manually and it will start if I jump the starter I have a little harness for different mowers, but with everything hooked up fuses checked, sitting on seat turn key nothing can the two fuse relays be bad? ow can you check them? I only work on mowers for friends not wanting to get in business just can't seem to puzzle this one out. I believe Collins in Enterprise Al. is the closest dealor to us.
