From my other recent thread, I was able to install my one piece crank pulley. I jacked up the front of the engine to gain access. With that said, I have a new problem that I think was caused from this activity.

I now find that my throttle linkage is such that the throttle won't rest of the idle screw on the carburetor. The problem appears that the linkage on the throttle control lever on the steering column is such that its holding the throttle open too much. The steering colum linkage for the spark advance still is fine, so something must have gotten pushed or bent when I raised the engine.

If I take off the linkage from the steering column to where it joins the accelerator pedal linkage by the firewall, then the throttle will go to its set idle screw position. I tried to rotate the steering column tube to pull the throttle linkage away and although that will then allow it to fully go to idle, it also pulls the spark advance, so its too far away from retarded. So it seems that moving the steering column tube fixes one and creates a problem with the other.

I assume there must be some adjustment somewhere that allows for proper linkage adjustment. I can't seem to see where that is. The springs that are part of the linkage around the steering column have pin through them, so they don't appear to be able to be rotated.

Is there some adjustment of the linkage length or position, other than rotating the steering column tube, so I can get both the throttle linkage and spark advance correct. Again spark advance is fine in its original position, its the idle/throttle linkage that is not allowing it to go back to its set idle position.
