I don't have advice about the RV12 specifically, but typically with any kind of fuel control system you should hit the stops on the carburetor or fuel servo before you hit any kind of stop in the cabin.
Based on that industry standard, it's kind of hard to know if you have a problem or not until you get the rest of your system installed.
edit- again, I don't have any experience with the RV12, but I took a closer look at the pictures and it sure looks like something isn't quite right for that to be hitting with that much travel left to go in the quadrant. is it possible that the lever might be installed backward?
