Hello,
there is nothing to be resolved. It is just needed to set Min and Max values correctly.
It just mean that your servo must work in reversed direction, for this reason you have to enable Reversed option in the window.
But still for servo nothing is changed so Max value will set the highest pulse value and Min. the lowest pulse value.

if I lower that number from 1900 to 1700 the carburetor opens further.
Then why you just not increase the number instead of decreasing?
These values are what servo reads, they will stay as they are even when reversed. But this does not mean any problem. That is how it works with all servos.
