Now, idle is idle on the carb, half stick is half open on the carb, and full stick is full open on the carb and full rpms on the engine! Before I was getting half open on the carb barrel with just a couple clicks above throttle on the stick. Didn't have to use any expo at all as most suggested. Incidentally, I ended up using the outermost hole on both the carb and servo ends.
I am glad you now have it fixed to your liking but you reported previously ...

The opening in the carb barrel IS proportional to the throw of the throttle linkage and arm. In other words, when the stick is at idle the barrel is barely open, when it's at 1/4 the barrel is 1/4 open, when at 1/2 the barrel is 1/2 open and so on. But the engine response isn't proportional. This is what I was trying to explain before. With only a few clicks (now) above idle, the engine begins to race too quickly. We put a tach on the prop and sure enough it showed the rpms of the engine were not proportional to the stick movement. There is a logarithmic response where the engine rpm's climb their most at the lower end of the stick movement.
Have fun with it.
