Good job!

Parts are a perfect fit. A little slow in the shipping but wasn't terrible. Husquvarna is a good product which services these particular Sears parts.

I thought I had broke the belt but as it turned out on of the pullies froze up which caused the belt to break. I love my weed-eater so it was important to have it fixed. My son did the repairs for me.
