Spring 90566944

This is an OEM spring located between the spool and spool cover of your trimmer. It is designed to hold the spool in position. This spring can lose tension over time and may cause the trimmer head to feed too much line or not feed any line at all, indicating the need for a new spring. The spring applies pressure to the spool, pulling it firmly next to the top of the trimmer head and lever. The lever is what regulates the amount of line coming out of the spool. This repair could not be any easier, simply remove the trimmer head cap by pushing down on the two tabs on either side. This will expose the spring, which you will see positioned onto a tab on the cap, and can just be pulled off, and a new one can be installed in its place.
