Black & Decker GRASS HOG....model GH700 14".....noticed lots of folks having trouble with this thing not feedind line....same here...worked great for about 3 seasons, then started feedin about 6" of line instead of the 14", not to great for edging....I replaced the spool cover assembly, which included the little black lever thingee (part no.905485530) & now its working fine again....the new part looks just like the old part, but must have been some wear somewhere, for $4.23 it was worth a try...picked one up at my local DEWALT dealer (they handle Black & Decker parts)....Hope this helps.....
