I hope this helps, my dad sent his carb to the carb rebuilders in Toronto, Canada. They did a wonderful job cleaning it and it worked flawlessly when he put it on. Didn't even need to adjust it at all.
sounds like the power valve is bad, unless you have already changed it. I would try that first. Also look up the procedure for drilling out the hole a little in the secondary butterflies. I had the same prob with a 750 and that did the job. When i say drill i mean very little just go up one bit size and then test. if you go to much at first you cant go back.
You almost never need to drill the butterflies unless you have a REALLY wild cam & need to idle at about 2500 RPM. LOL Adjust the secondary idle speed up instead.
