Singer 404 and 401: stuck needle plate/feed dogs! How to unstick and oil this problem back to new

Thank you! I'm not positive this was the problem on my singer 404. However your video was very concise and informative, keep them coming!

Hmm, is this intended to show us "something"... The tension mechanism is messed up completely. It is oddly "upside down". Really ??? That machine was obvious "butchered" by some unknowing "repairperson"..
