Well, Glen you are right. I took off the clamp and that bar is visibly cocked - the clamp screw is forward - it fits in a hole so I'm sure it is off. I could not find an adjustment screw at all. I should not fix this tonight. The only tool I can think of is a hammer. I so do not want a parts machine. NOT TWO IN ONE DAY. There has to be some kind of adjustment for that shaft.
