Hi, all.

Having an issue that I haven't a clue how to troubleshoot and I'm hoping someone here might have some good guidance. I have a "full" bobbin that has been inserted into the machine. I manually run the needle down and back up and it "loops around" correctly to grab the thread. I lift it out, move it to the left and back, and slide in a piece of cloth.

Once the machine makes 1-2 stitches, it basically jams and the needle will not lift up all the way to complete the cycle before going back down. This happened once before and I pulled off the plate and brushed everything out really well. Upon reassembly, it went back to working very well for quite a fair amount of use until today when the problem occurred again.

This time, cleaning it out thoroughly (and it was very dirty again with fabric dust like last time) seems to have no impact and it's still jamming within 1-2 stitches.

When this occurs, it appears to be the top thread that is getting caught somewhere under the plate. Thoughts? Ideas?
