Wheel adjustment screw

Question

Nowhere on this door can I find a Brand, model nothing.
The screen door started dragging. I tried tightening and loosening the screws at the bottom of the screen, it wouldnt raise or lower. I popped the screen off and there is nothing inside for the screw to contact to adjust the wheel. Picture 1 and 2 are the door. Picture 3 shows the wheel.
Picture 4 shows inside the bottom of screen. I dont have the screw in. What is supposed to go inside the screen to adjust the wheel?

I'm not sure myself what to suggest. Take a look at the other roller and adjustment screws in the door to see what their setup is. It is possible that all you need to do is to install a screw into that threaded sector at the bottom of the door that you show in your photo. I also recommend that you take the screw to a local hardware store to match it up.
