There's a video on the ABM website that shows you how your bobbin should sit inside your bobbin case and how to adjust the springy thing on the bottom, just have to bend it a little.
This is so confusing and frustrating to have different techs and repairmen saying opposite things.
I took the spring out of my bobbin case and my tension issues cleared up and I haven't had any more problems. I was told by a tech to take it out and use a bobbin geni washer instead. When I took it in for a cleaning the repairmen put in a new one,said it was missing. He said the tech was wrong. I said well it works for me so out it came.
The tension spring is easy to remove and put back. I took it out of my Bernina and Brother 1500.
