Thanks for your reply. It is the shaft on the left photo. I have turned the adjusting bolt in and it makes the angle worse. Turning it out does nothing. What I need is to turn the shaft the opposite way. When you say you should be able to turn the shaft into any position that you want, it seems to me on the one I need to adjust, there is only about a five degree change in the adjustment. and only in one direction. Thanks. Marv
