anyone know how to rewind a Universal Products spool....it's a dual line model , and on the inside it has the letters L & R (left and right) and CC & C (counterclockwise and clockwise). The weird thing is the spool head has the nut in it so when you go to reattach it, it will unload string from spool and pull string out the the feeder holes. I know it's got to be quite easy, but this is pissing me off:freak: thanks
