Thanks for the input.....you were on the right track. What hurts is that the problem was my fault.
Before I get into that, a couple of things. I mentioned earlier that I used a plastic semi-funnel to take the gas from the bottom drain to a container. It worked but was hard to keep in place, etc., so I went scouting in my shop and came up with a piece of aluminum angle.
See the end of it right under the float bowl drain, like a letter V ??
It worked perfectly - could even remove the drain plug with it in place and spilled zero gas. Smart Lar.
Now to the problem. Not sure if this was the entire problem, 'cause I did finally get it to run a bit on throttle but it was still very bad. Then I got looking at the pink tube that runs along the frame rail over the air box. It went "under" the frame rail and I was kind of musing, "hmmm.....wonder what that's for ?? Maybe a vent ?? Maybe it's pinched ?? Take another look at the top photo with the V under the carb. See the pink hose right behind the rear corner of the gas tank ?
I pulled it out from under - it Was pinched.......and the bike started right up and ran great. Of all the damned things ! ! ! Must've done that when I was trying to get the air box out to put in the shock and spring.....which I found that I didn't need to do. Well.......it's a lesson, eh ?? That's why people call me "Stub-Bourne," a play on my surname.
P.S. The bike rides a lot more solidly and feels more....taut...??...precise...??...whatever, I can sure feel the difference.
