Hi Paul,

Thank you for your response!

What you're saying, I believe, is that I identified the WRONG screw to set
less tension on the hinge...right? If this is so, I should go back and
first reset the allen screw to the same position it was in...clockwise 1/4
turn. Then increase tension on the stop screw you describe. Have I read
you correctly?
