Ok, I took some pics maybe these will help get me help..?

Also, I got some important numbers wrong..sorry! Her thread is all 40wt and mine is 50wt. Except for the Coats Surelock threads I have, I have no idea what weights these are as it doesn't say anywhere on the label.
All threads, hers & mine, are right twisted as far as I can tell. Her labels say that, mine don't but I did test the open ones and they are the same twist as hers are.

First pic is the machine, threaded according to the guide I found and it works this way so it must be right.
2nd pic is my stitch plate/bobbin cover area. Both are solid except for the tiny hole for the needle to go through. No feed dogs either.
3rd pic is two spools of thread, made in different years. Hers on left, mine on right.
4th pic is the label on her spool of the white thread, but all her spools have the same type of label. Some are this brand others are JP Coats.
