This is a genuine STIHL recoil starter spring — the spiral return spring used in the recoil starter assembly of professional cut-off saws. It restores the correct rewind tension so the starter rope recoils smoothly after each pull, improving starting reliability and reducing starter fatigue. This OEM spring is precision-wound to STIHL specifications.
