This might have been the most stubborn part so far. The carb roundslide was completely glued in with old fuel. It took a few hours of chemicals, hot water and gentle coaxing with a tooth brush handle to free the slide. Then every removable part was removed, cleaned and polished and oiled with synthetic motor oil. The barrel and roundslide now have a mirror finish. I ordered a complete rebuild kit that includes, air screw, needle, both jets, float needle and seat, and all gaskets. Good times. I'm excited for that kit to arrive.
