Atomic Leathers, I know this thread is old, but I thought I would give it a shot. I just bought a cobra 26 and i am having the same trouble. Did you find a solution?  I knew there would be some markings but from all the videos I watched, my markings are a lot worse. Also, when I press on the pressure foot pedal it is barely lifting the foot? Something is definitely off but I'm not sure what. 

Well, it sounds like your chain needs to be taken up a link or however your'e adjusting it.

First thing you want to do is see if you can back off the pressure on the feet.

if that doesn't work, Sometimes you have to think outside of the box.  You can COUNTER the force of the feet if it's too high by attaching a light spring from the hardware store to your lift chain and then somewhere on the table (pulling it down).  Don't use a spring heavier than the one in your machine, you just want to reduce down pressure.  

I've made pressure extremely light this way on a couple machines. Light, but consistent.   If you're using a very large needle with large thread, you could run into issues with a very light pressure on the feet.
