Perhaps they used Kevlar thread?

Possibly, it must have been pretty abrasive whatever it was.

Check your bobbin and tension plates as well for grooves.

The tab on the bobbin case needs to be in the notch of the feed dog.  Raise feed dog enough to rotate into position.

The fix on the take up lever is working well, the tension is now consistent up to the needle like with my other machines and I had to tighten the tension way more than before as my issue for the first time became loops on the bottom. However something hunky is still going on and it’s the bottom tension I think as although I know bottom tension is light, it’s virtually non existent.

good call! There is indeed grooves on the thread guides but not very deep so I could just sand them out and I took the spring off the the bobbin and there is a groove which won’t be helping.

Thankfully the casing looks ok so I will just replace the spring and screws

I have no idea what this machine was running but it has very little slop on the internals so I’m thinking it was just a very abrasive thread. Hopefully replacing the spring wills finally solve the issue.

When I put the needle plate on I do make sure the notch is in there, I had spun the casing to get to the spring in that photo I think, thanks.

thanks for all your help guys I really appreciate it.

Yes. Make sure that you install the needle/throat plate with the cutout facing the shuttle/bobbin case. Before you fully tighten the two screws, place the bobbin case tab under the detente, then tighten down the fore and aft screws.

Just an update, sorting the spring and thus sorting the bobbin tension has solved the issue. I now have a pretty good stitch

many thanks all
