Trying to load pre-would string reel. The new one came with a small amount of tring tucked into slots in the reel. I pulled the ends out and strung them through the eyelets in the trimmer string housing. However, it does not realease when tapped. I must have not dealt with the string in the pre-would spool and the outer string housing eyelet holes. Also, I cannot seem to get the string slots lined up exactly with the housing eyelets. Must the be exactly lined up for the self feeding to work?
