I can't quite tell for sure, but it looks like it is threaded correctly. If you have it threaded like in the video referred to in other forum, take notice of where the red notch is at on the tension dial. In your picture it is right above the Zero "0" In the video it looks to be at the line past the three "3" at about 4. While I said "The tension dial should probably be set so the number 4 is at the top." I was partially wrong as it is not that number should be at the top - the red notch should be at about 4. After you have it threaded through the needle, lower the presser foot. Gently tug on the thread. You should feel some resistance, but not so much. Archaic Arcane has a good page about upper tension at
https://archaicarcane.com/fragile-te...-equal-stress/ While she is working with a Singer machine, which is slightly different as the dial turns so that the numbers are on top of the dial, the principle is the same. The dial needs to be turned. On your machine the outer wheel of the tension dial turns so that the notch moves.
Hopefully, we will get you sewing properly, soon.
