Hi and welcome to JustAnswer,
Im so sorry that no one else has responded to you.
Apologies for my delay in replying, I only just came online and saw your question. Are you still looking for help with this?
Hello, Yes no one had responded yet.
Where is the looping portion above or underneath the fabric?
Have you try to re-seat the bobbin case and bobbin. make sure it lock firmly.
can I send a short video of what it is doing? I will try that now.
It will thread the needle but as soon as you turn in on it starts running making noise. If I put the Thread Exchanger on it will flip the bales up and down. Nothing will stop this from running. Like I said the machine was never really used I still have the receipt from 2004 when i bought it for my wife new.
The endless loop is the noise it makes it is trying to run the thread exchanger when it is not even on. If I put it on the thread exchanger and turn it on it does the same noise but will run the bails of the thread exchanger up and down.
Upon powering on it should not do anything until you push a command button.
Here is a link to a video of it running from start up.
