The flower nut is not what is responsible for how tightly the clutch pressure plate presses against the friction discs. That job is done by the clutch spring which is inside the engine cases.
The flower nut is there to allow for clutch adjustment as the friction pads wear. That said, the flower nut does need to be set correctly for proper operation before the clutch will function properly.
