Default 1949 F-1 carb linkage trouble

I am working on a 1949 F-1 V-8. It was restored about 30 years ago and used very lightly since. As far as I can tell it has been kept pretty much the way it was built. It has some issues that need to be sorted out, but it runs and drives pretty good. The most serious drivability issue it has is one I hope you can help me with.
When you push on the gas pedal there is a resistance, with no RPM gain, and then no resistance with a lot of RPM gain, leading to some very jerky starts and less than smooth shifts. I believe that the problem stems from the position of the arm on the throttle shaft that has the ball end on it. The throttle linkage from the firewall to the carburetor is trying to pull the ball straight back coming off idle.(instead of in an arc) This causes the two spring loaded ends of the throttle rod to stretch out, and after forcing the throttle shaft to rotate clockwise a degree or two, the springs return, and the throttle moves just the way it should. It appears that the arm on the carb with the ball on it may have been loose at one time, as it looks like someone may have peened it back in place. So my first question is does the throttle arm on this carb look like it is in the correct position? Thank for your help.
