Wrong Spring Ordered and received twice.
Need spring for the B&D GH3000 grass trimmer that fits goes on the spool section of the trimmer. If you have one please let me know. I think the part number might be 90588959. I now have 4 springs 90559866 frrom ordering twice and thinking they were the right one.

None of the parts that I received worked with my weed eater
The parts did not work. I have had a lot of trouble with Black and Decker weed eaters . I became frustrated and threw the parts and the weed eater away
