Yes! So much of that video applies to so many machines. It's possible some individual specs may differ, but the adjustment procedures are the same until you get to the hook settings obviously. As for the specs, the singer 111-156 manual has a little better explanations of adjustments and illustrations than the consew 226 manual, but i wasn't able to get it to upload, a google search should find it easily. First thing though is to tip it back on the leaning post and turn the wheel until the take up lever is at it's highest position and hold it there with your left hand so it doesn't move. On the bottom right side you'll have timing marks like this
2 arrows should be aligned. If the timing belt is a tooth off, no other adjustments matter.
@Smooooth nice score!
