According to FW Doctor
Shoot, I tried to edit and took to long so will try again. The link for the quote should have been Singer Featherweight 221.
  1. Check the belt tension.
  2. Check the brushes, and commutator for deposits
  3. Check that the bobbin is disengaged.
  4. Check the foot controller.
  5. Check the motor pulley that thread isn't wrapped around
  6. Check the hook area that there are no threads.
The FW Doctor link is for #5
For #4 a video is at https://vimeo.com/146051184
for #6 the video at https://www.youtube.com/watch?v=ylxQmI_R-2A is probably the one that I watched when I was having trouble with a FW that would speed up after running for a while as described in post #12 and #15 of FW-HASB ?? fixable? by me? - very long winded
Andy Tube has a longer one at https://www.youtube.com/watch?v=1yVQ0NkcUzQ
