Northmount,

Thanks for that. I did previously remove the strip entirely, it does appear to have a smooth/unbent shape, and does appear to clamp down properly when the screw is tightened. There was nothing under it to cause problems. I am tightening the one closes to the exit of the thread as it is the one that makes the strip flex. I had thought the thread was going under the tension strip, it was hard to see so I did verify, it is going under the tension strip. It is still freewheeling.

Does the 227 use a spring inside the bobbin case? If that's missing, that will allow the bobbin to "spool"

IF what you do is something that ANYBODY can do, then don't be surprised when ANYBODY does.

The more I looked at the machine in operation, the more I became convinced there was something wrong with the tensioner spring in the bobbin case, so I removed it and tried to flex it.

Not really a spring steel metal as you might expect, since it bent easily. So I gave it a bit more of a curve, and reinstalled it. Voila, there was a bit of resistance on the bobbin thread once again, and I could adjust the tension by tightening/ loosening the screw. Success there! I feel the tension is still uneven as the knots don’t alway sit correctly on a single run of 2 foot stitching, but it is much improved. If I can find a new one to replace it, I will. Any ideas on further improving tension consistency would be appreciated.

Thanks,

YinTx
