I think I found the problem - after conversing with Mr. Silver, he suggested that maybe the fuel needle was too long, and indeed I think it is. The differences are minimal, but they are there - the old needle is slightly longer, and the shoulders of the old needle are flat while the new needle is shorter, and the shoulders are rounded. It makes a difference!
I changed out the old stuff that was in the carb (PW22, btw), with a new carb kit (Keyster KH-1316) and there it was - positive fuel flow! Whooo-Hooo! I believe somebody down the line put in a CL72 or CB72 carb kit, and I wouldn't be surprised if they just said "F--- it" after it wouldn't start.
Luckily I had the KH-1316 kit laying around, which I think I bought years ago and misremembered that I had put it in, when I hadn't - so I went digging around again for the KH-1316 kit, which comes WITH the #120 main and #35 slow jet, and so far only have found ONE source for it - Classic Honda Restoration.
They have the Keyster KH-1316 kit for $21.95 + $9.00 shipping, so $30.95 all-in for the correct carb kit. Nice site, too. Oh yeah - (and I don't know why I didn't see this before) - the needle seat was a 2.5, not a 2.0 as it should be...
So while I would like to call this problem Solved, I will update once I again try to start the beast, hopefully this week after all this rain moves out of here and it gets warmer.
Also, after looking at a pic of my carb, Mr. Silver said the tang should not be way down against the needle, the way I had it - and indeed, with the new carb kit it is Not, now, and the floats are at 26.5mm - did I mention I have positive fuel flow?? :)
I will report back and let you know what happens, although I'm sure something else will rear it's ugly head...

Carb Won't Fill
I *Could...but that would ruin the surprise...
No, actually...once you get over the fear of 'What's going to happen after I split the cases? Will God be offended?" it's actually pretty interesting to see how everything goes together. It's even More fun to try to find parts made out of Unobtanium and having to fabricate them yourself, like main-shaft grooved bearings that sit in the cases...or a better solution to the POS fuel petcock, that I made made out of thick aluminum discs and screws...or seat brackets that SHOULD be there but aren't...yah - Good Times. I didn't do it with this CA77, but I also have a CA95 that I literally built from the cases up. Wasn't cheap. You got to love old bikes...it's true: you gotta...!
