212 engine throttle linkage - What am I doing wrong?

I can't figure out what I have done wrong in setting up the throttle linkage. As you can see from the attached photo, the rod on the left side of the engine pulls that arm through almost 90 degrees of rotation before it contacts the adjustment screw on the bellcrank.  From all the grime on the threaded part of the throttle rod, I can see that the adjustment hasn't changed in years, so either I have connected the pieces wrong, or the throttle rod has been adjusted wrong for a very long time. (It doesn't actually look like there is enough thread to compensate for the huge amount of travel that has to happen before the bellcrank is engaged.)
I tried putting the throttle rod in the lower hole, but that hole is 1/4", and a 1/4" clevis pin that fits through the lower hole does not fit through the hole on the end of the throttle rod.

    I think your missing a spring between the two holes in your photo?

    It's been 35 years since I had one. Go to the online manual and check the parts book and adjustment section of the repair manual.

    This isn't precisely "correct" Hudson set-up but it works very nicely.

    It is most definiatley the spring that is missing. The 212 in my 39 has the same set up

    My 40 has a very different setup. Mine has a rod about 6-8 inches long that is attached to the gas pedal and comes through the floor pan where it attaches via cotter pin to a long adjustable rod that makes a 90 degree turn and goes up to the throttle linkage. The throttle linkage crosses the engine to the passenger side and connects with the carburetor. My spring is attached to the linkage that goes across the engine.

    Do you have the manual for your year car?

    I disconnected the throttle rod from the pedal and the bellcrank, to see if it would behave better if I flipped it over. That was a no-go. But when I put it back together, for some reason it took up most of the slack and the return spring now has some preload. Then I added the missing spring and the throttle mechanism is working nicely.
    I really don't know what I did differently, other than the fact that the throttle rod is now on the inside of the bellcrank lever rather than the outside. (I seriously doubt if that makes a significant difference.)
