I have a 153w103 and its sews well, the issue I have is that the feed dog and walking foot meet below (almost 1/4") the needle plate, which pushes the material (chrome tan leather and canvas) down into the needle plate. Is this normal or is it something simple like ordering a thinner needle plate? I raised the feed dog height, but all that did was make the material lift higher in the back and seemed to put more stress on the walking foot. Please find link below for the short video I made showing the issue.
