What the heck does that mean?

In the picture, if you look closely, you can see that the throttle shaft ball pull linkage end on the left hand carburetor is about 10 degrees more clockwise than on the right hand carburetor. I want to re-clock the linkage end on left hand carburetor to match the right hand carburetor.

Why bother? No one will notice. We'll, you can't see it in the picture, but on the left hand carb, the accelerator pump rod is acting as a stop preventing me from reducing the idle speed with the idle speed set screw.

No doubt I could remove the throttle rod, clamp it in a drill press and drill out the "rivet", or whatever it is, attaching the crank to the throttle rod and reattach it in the desired position. I've heard silver brazing might work but I have no idea where to find someone with that skill and equipment. Is there another way that's easy to do with more common tools and materials?

Before you ask if something else could be wrong, possibly, but I don't think so. Yes, I used a Unisyn to sync up the carbs and I don't think there's a vacuum leak. If I block off either carb, the car chokes to a stop. Don't think the idles too rich either. The plugs are clean and even an eighth of turn in on the screws chokes the car.

Suppose I could just buy a new shaft with bushings (the only ones I can find are oversize) and new throttle rod end that "locks" with asquared shaft, hole and a screw. Don't really want to get into replacing throttle shaft bushings. Don't know the diameter of my current rod, my micrometer is a cheap mechanical model and I get different readings if I use the metric scale or the English scale and convert back and forth. Don't know which scale is more accurate. Of course, I could just buy a new micrometer and I just might do that this afternoon anyway.

I've probably answered my own questions but just checking the 'Barn to see if anyone has gotten into this before and could offer some advice that would make this easier or save some time.
