I'm trying to visualize your plan in my head. Frst, you can't use a longer lever, and attach one rod to one hole, and another rod to a differant hole higher up. That changes the range, and your balance would be off. It's really critical that all levers and attachement points be exactly the same.

If I understand yout linkage arrangement correctly, there's nothing wrong with it. That's not your problem. If the throttle shaft is twisted, something is binding inside the carb. You have to find and fix that problem. Don't waste any time or effort changing the linkage.
