I took it apart to clean and look for "things that don't belong in there". It is making a clunking noise and bunching stitches unedrneath.
I changed:
1. needles (universal, ball point, heavy jeans needle-all new from the packages);
2. thread from Gutterman to Coats and Clarks (my usual thread)
Any other tricks I can try? Machine i useless but clean!
Mine was making the clunking sound too. I took it to my LQS to have it looked at. They told me it's because the uptake lever was going bad. It wobbled back and forth, which threw my bobbin tension off. The clunking was from the uptake lever and the bunching stitches was because my bobbin tension was off. They told me it would need to be replaced. They also told me that the motor was going out so it wasn't worth fixing.
