Worked on it more this afternoon. The trick with the sync screws did not help. Now the choke does nothing. I never touched air/fuel screws or idle jet. Now you need some throttle to start it and hold it for a while, then it idles again at about 2000+. Cylinder 2 is NOT getting hot still. I will pull the carbs again and try to sync the butterflies. I found an excellent article that discusses rebuilding these specific carbs.
