I just bought a singer 360 knitting macihne that was totally jammed that i disassembled and cleaned and oiled and now it will only knit left to right but drops 95% of stitches the other way. I was only able to remove the lower drum on the carriage and then the screws stripped so i was not able to fully clean it. The drums on the left side are moving freely and on the rightly slight less but i don’t have to use very much strength to move it either direction. I did not 100% disassemble it i cleaned the middle/lower drums only. I didn’t look at the cams at all. Any suggestions of what might be going on? Trying not to destroy the screws I stripped to get at this one drum but if I have to i’ll consider it. The seller had no idea about the machine she was selling it for family. There is also a gear that is less freely moving on the sinker plate but again it has a stripped screw. I cleaned a WHOLE bunch of wound up yarn from it and it is 80% better without being able to unscrew it.
