I bought a torch. I used it to heat up the carb bodies for maybe 30-60 seconds and the slides came loose. Amazing. They were a tight squeeze when I tried to fit them in the carb bodies that I planned to use. There was still a lot of sticky junk on them. WD40 didn’t take them off very easily but my finger nails did. I scraped them clean (as best as I could) and they now slide into the bodies just fine. I really wish I would have tried this torch earlier. It would have saved me from buying a new diaphragm. Hindsight = 20/20
