The threads on the flower nut are in place. It's just the threads on the shaft are so poor as though the shaft was too small a diameter when they cut threads onto it in the first place so that the flower nut does not thread onto the shaft properly. Either that or they cut the threads in the flower nut too big. There is so much play between the threads that when the flower nut is threaded on I can actually rock the flower nut side to side quite a bit and the when the clutch arm is released the flower nut simply pops off from the spring pressure.

I've atached a simple picture for illustration. Picture A is the way my threads are and picture E is the way they should mesh. Obviously I've exaggerated picture A slightly because the threads on my engine's shaft/flower nut do mesh but just ever so barely so that there's not enough force to hold the nut n when the clutch lever is released.

McGyver could fix that with bubble gum.
