I have a single line auto feed weed whacker, that I've bought replacement line for.
The problem is that the line I bought is wound around a spool thats about 10cm in diameter, so when I wrap it around my line trimmer head which is only 5cm diameter, it "uncoils" inside the head because it tries to spring back to its manufactured coil. Basically that means the line thats extruded gets sucked back into the head.
How do I coil the line tighter so it behaves itself inside the trimmer head
