Just got a 327k and I messed it up!!!
Edit/update: as mentioned below, I purchased the service manual and watched many videos on how to fix this issue. After reading the service manual for the 4th time from concert to cover, I figured it out. Needle positioning instructions as well as tuning the arc of the needle as instructed in the service manual did the trick.
I bought this beautiful 327k for $60. I bought it for it's zigzag ability but it won't zigzag after I took it apart to clean it (it doesn't look like it had ever been cleaned. I put it back together with only the left over part in pic 2. Everything works as it should, except the stitch width lever keeps popping back to zero. I took video of myself taking it apart and took pictures, but I apparently missed talking video/pictures of this part. My hand also blocked the view for the majority of the video 🤦🏽. I paid for a PDF of the service manual and searched the web extensively for a solution and I'm still haven't figured out the problem. Please help!?! I really want to get this thing assembled and start sewing. (I can't seem to add both photos and video)
