Have you come here seeking help with actual tension issues?
I’ve noticed that that’s one of the top searches that brings people here. Plenty has already been written on this subject, so I won’t burden the interwebs with another list of the same old things. Here are a couple of good lists. And if none of these things work, then I think the best thing to do is to find a forum online for your specific model of sewing machine and ask other people who have expierence with it.
