Hmm. I've owned a Winslow for years -- two in fact, one for tenor and one for bari -- and though at present I'm using a Francois Louis, I may go back to the Winslow any second now. I've used Winslows on several different mouthpieces, always with excellent results, and have never fiddled with the setup: I use it in the configuration it came in. This is no help to you of course, unless the problem is that you've adjusted the lig so much that you can't find your way back to square one (I've had that happen to me with a lot of things, including a Rubik's Cube and my first marriage!).

The four corners configuration is the way mine came, and it works great for me.
