Hi MaxG
This is an automatic release bump feed head for straight shaft. The metal bit in the middle is the slider. When you bump the head while spinning, will momentarily drops the slider and disengages from the upper ratchet plate which in turns will free-up/slow down and unwind the reel and feed the string out. Possibly the slider 8 teeth doesn't engage with the top ratchet plate due to not enough spring compression/tension. Manually spin the top ratchet counter-clockwise (looking from the gearbox perspective) if it engages with the reel assembly. If not, stretch the spring just enough to engage the slider with the ratchet. Your winding of string and assembly is correct.
