At my wit's end

Yup. Applied the grease. It isn't a dielectric grease but a heat compound like found on computer CPUs. From what I've been reading about he problem I'm having it does sound like it is probably the carb. Hoping Dan has the right replacement/NOS 1920 and I'll just swap out the whole thing. Otherwise I'll try the new float and go from there. I'll still grab a new HEI module or two this weekend since I need one for my 67 Ranchero too. Heck, I might have that car running before the Dart at this point.
