If you're serious, and willing to wait, I will come get it in the spring / summer. We've never been to Saskatchewan.
I may have a friend who has family there too. PM me if you decide you can't stand the machine after we troubleshoot it and we'll work something out. Which black machines are you still wanting? I have a couple duplicates and a different "market" to pillage from.
That said, it looks like you don't have the bobbin case in correctly. There's "groove" on the bobbin case, it needs to straddle the ledge on the inside of the hook. It looks like you have it under the ledge in the photos. When the bobbin case is correctly positioned, it will almost "disappear". The bobbin case will be flush with the top of the hook, all you'll see is a seam between the two. Once it's in place, and you put the "removal arm" back into place, it will hold everything tight. Put the screws underneath back to tight. Those (if I'm looking right) will put your timing out if you operate the machine with them loose.
ETA: Don't operate it until you have them tight and turn it one full turn with the hand wheel. If the hook moved at all while the screws were loose, it won't stitch or the needle could strike the hook and break. I will walk you through re-timing it if needed.
