To properly thread the top tension;
Thread from the spool passes through the thread guide at the top of the head, down under the tensioner on the right side. Up the left side, over the spring, down under the hook, then up to the thread take up lever. Through the eye of the T-U lever from right to left, then down through the guide on the face plate, through the guide on the needle bar and through the needle from left to right.

If the little spring is down way low on the left side, it can be adjusted.
