mate, you and me seem to be in a parallel universe!!!
mine has been spinning last 2 weeks, and winding me up a treat, kept tightening it, but it kept loosening itself off again, so i rang the supplier, as the bolt was spinning in the lever, and they are sending a new lever and nut and bolt out to me.
i thought the section must have worn out, but it's only 3-4 months old...
