OMG, Joe, I was going to pm you with the same question. I have a 127 that is gummed up just like yours. I've used kerosene and WD40. I'm about to pull my hair out. They're so many parts that I can't reach. I was going to ask you if I could spray oven cleaner up inside her, then flush with hot water. She is frozen up, not rust, just gunk. I've also tried to use a blow dryer to heat her parts up, but that didn't work. She's a treadle. I was going to put a handcrank on her. HELP!!!!
