Question about Viking Mega Quilter
My sister recently gifted me with her Viking Mega Quilter machine to thank me for helping her with her shop. My problem is that I've been trying to sew with it and the top thread either keeps getting broken or the needle keeps coming unthreaded. She has said she thinks the tension has gotten messed up. I've tried checking the bobbin case, changing spools of thread, changed the needle so the tension is the only thing left that I can think of but getting a little frustrated as I can't seem to figure it out. Tried looking at youtube for tutorials, but come up with lots of videos unrelated to my question.
Does anyone have any suggestions. Machine is very nice and she even has a quilting frame that I might look into some long arming eventually. Help would be greatly appreciated. Thanks.
