u/Disastrous_Fly7700

Hello all, i've been refurbishing an old Knitking/knitmaster 4500 and until yesterday was getting it to knit pretty smoothly. I was in the middle of knitting a sock when the machine started dropping stitches, and is now making these small loops on the front of the knitting. I was hoping that someone here might know what is wrong as I've checked the machine over and can't see anything that I've bumped out of place or that looks different to when it was working fine before. Edit: picture in comments because it wouldn't let me add to post.
