Great Website, Fast Shipping, I Just made the wrong Diagnosis
I really don't know if the part worked or not as that turned out not to be the problem. The trimmer still doesn't work, but I was just taking a guess as to what was wrong.

Long shot.....
The part was the right one, the service was super, but it turns out that it didn't fix my weed trimmer as the motor turned out to be the problem, not the start switch. But I'm pleased with e-replacement and am sure I'll use you again.
