Edelbrock carb throttle linkage on a 318

That's crazy that you posted pictures of you doing this, because last night I did the EXACT same thing! My timing is still a little bit off. I put the bolt in almost the same position as yours. Shifting to second from first is off. Would I adjust the bolt on the arm, or my throttle cable? How do you determine the location you put the bolt? And you're not going to use the same throttle cable, right? Assuming it was a 2bbl to 4 bbl conversion. My cable seems too short, it won't connect at the same point on the housing of the metal now.
