Found this thrifting, not familiar with the brand but seems like a tank it’s so heavy….I’m thinking it’s a good deal for $25 with the case, tray, foot pedal, manual, cams (I don’t even know how to use) but just a quick plug in seems to run ok except the top left knob seems stuck on that button hole selection (the other two knobs turn ok) and it won’t move at all. Is there a trick to it, does it need repair, or just old stuck oil stuff? Any suggestions to get it unstuck would be appreciated.
