I was able to adjust the idle by dropping the sync screws on 1/3/4 carb. 2 was not getting hot, so I think that was the right thing to do. 2 is now getting hot. There is no way to sync these carbs with a normal gauge since there are no tube on the intake side. The idle screw now works as well. Just don;t know if they are in sync. But for now, I am good.
