Day 1 for its annual and on a positive note there are 3 other beautiful Mooney's in for service. One of the things I like about doing the owner assist is I get to hang out in a shop full of Mooney's I think I might post some photos of the work. Any way hear is a question for all you mechanical types out there in Mooney land. All was going well but when we were inspecting controls it was found that the carburetor was not going to full throttle position on the butterfly actuator arm. We disconnected the cable to see if that was the problem but no. After removing the carb you could see that the butterfly was only opening to about 7/8 and would go no further. The plate was secured tight to the shaft and nothing could be seen that was hanging it up. It will most likely have to go in for repair. Any thoughts on what might be limiting its travel
