Things that I have done so far:

• rebuild carbs (enrichener properly assembled and butterfly valve installed in the proper position)
  valve adjustment (triple checked!)
  new points and condenser, and timed!

My last step is to adjust my carburetors. I have read snowbum's article on carb sync but my idle is way too fast. My idle stop screw is not engaged at all. My butterflies are shut. When I adjust my idle mixture screw to fastest RPM, bike will idle to 2000rpm.

In the video I have linked, you will see the bike idling at around 1200rpm because my enrichener doesn't bottom out. I manually push the lever down and you see my idle rise to 2000rpm. I adjusted my carbs with the choke FULLY off.

I don't know what else to do. I have read Duane's and Snowbum's articles on how to fix fast idle but I don't know what I am missing.
