At the last minute they called and said I needed to take another machine to school and none of my spares were ready to go. So, I took my 503. It's a cabinet machine, not a portable, and I took it bare, without a case as it wouldn't fit in the only case I had. I can't remember for sure, but I think it fell over in the car.

Before it went for the ride, it was sewing just fine. (I double checked what I had been working on and it looked good.) Not so, today. I can't get the top tension to tighten up enough. If I turn it all the way down, it is still bumpy on the bottom side. It's a double needle machine, so it has two options for the thread path. I tried both. I've threaded and rethreaded it, but that's not the problem. You can feel when you pull the thread on the needle side of the tension that it's loose.

I've watched a couple of youtube videos on tension, but they don't seem to address this kind of problem.

Any idea where to start?
