Finally, to fix the sloppy pin pivot, I used a small drill bit to open up the hole to accept the next size larger machine screw I had in my parts box, I think it was a #4 or 6 screw. Then I put in the screw and a small nut and tightened it down just enough to pull in the two tabs on each side of the pivot. With the sides held tight to the pivot, there is no wasted motion. End result, the door now opens with the pressure of a single finger, success!!!   (5/5)
