Hi all. I am very new to my Pfaff 335b (old casting). I have the manual and hunted through hundreds of videos and posts and I am having trouble with the stitch length. The machine was transported via trailer so my feelings are that something has come loose somewhere. I know that the maximum stitch length for this machine is 5mm at best, which is fine for me as I don't sew extremely thick leather or vinyl. My issue is that I am only getting a 1-2.5mm stitch length. There is very little forward motion of the middle foot and it feels like it sticks at a certain point if I am hand cranking it. Before I do a 10hr round trip to my nearest repairer, does anyone have any suggestions, please? Bear in mind I am mechanically challenged. I am also new to this forum so not sure how to upload a video. Is there any chance someone can post a video of the motion while being hand cranked or a link to a video? Thanks in advance!
