I have come across something that does not make any sense to me, that is "if" the machine is working "properly"... I think. Maybe this is what I should be expecting though, yet is only on this machine and not my other one. I have to preclude this with it may be an issue yet what ever magic is at play here I am happy with this outcome.
This is my Husqvarna 120, and it does not matter if I use cotton or poly thread, lightweight or heavy. I am getting a nice stitch as far as tension goes, (see photo) but I thought that if I adjusted teh tension, it would change the balance of the top to bottom threads causing one to be pulled more to the opposite side. I put red thread in the top and black in the bobbin for this test, then changed the tension dial from 0 up to 10, 5.5 is the factory dot recommended setting. The result is the same no matter what the setting is. I get the same balance between stitches at 0 or at 3 or 5.5 or 10. No change. I compared the result to the Brother machine, and the Brother does change as expected, getting a pull through from one side to the other, dependent on the tension dial what side. If top tension is high then the lower thread is pulled into the top and vice a versa.
The Husq 120 has an issue then I believe, yet gives a great stitch. I am not ready to fix something that works just to have the give and take unless it becomes a problem. So I am asking the experts to offer their thoughts and opinions here. I can not say comparing the 120 to the Brother is apples to apples, as the 120 is not computerized, the Brother is.
Thank you in advance
