Recently purchased a 153k103 cylinder arm walking foot machine. The machine worked fine days before I picked it up and brought it over to my place. The walking foot is stuck in the up position and lever behind it isn’t working, no tension. The pedal is connected as should be but I don’t feel any tension whenever the pedal is pressed, I have a feeling something is stuck. Not much of a mechanic and the manuals don’t explain much on these matters. Any help would be greatly appreciated!
