"2. There's this screw dial thing on the top of the machine. It looks like it only affect the tension of the presser foot lever. Does it perhaps have another purpose that I'm not seeing?"
It changes the pressure on the presser foot for different fabrics or layers of them.
3. There seems to be a screw hole on the back side of the machine (near the presser foot lever) that doesn't have a screw in it. It doesn't look like an oiling hole either. Do you guys know what it's for? Am I just missing a screw?
"Are there threads in it.?"
