Combines Sticking solenoidIJ

You are likely talking about prior to '80 machine where there was a spool for auger swing that ran lengthwise with valve. Never had to remove one for sticking or anything and doubt there are any orings involved. I would doubt a problem in spool but would lean toward bad leak in poppet valve for whatever reason. You will likely have to remove solinoid and poppet kit to clean and replace bad seals. May need to get experienced help to help you out. Good luck

Had n6 valve apart and found a small piece of metal at tip. Removed metal, reassembled and worked fine.
