Help Install New Rochester Varajet 81' Cj-5 Iron Duke

Hey folks,

Could use some help from someone more knowledgeable. I swapped my rochester varajet out with a new one and ran into a couple issues.

1. The carb doesn't return all the way to the starting position when I press the accelerator pedal. It moves a little in the right direction but the fast idle screw is no where near contacting the choke.

2. When I gave it a test start it was idling way too high. Which I believe is because I had the fast idle screw screwed all the way in but I'm not sure.

So I'll add a couple picture to help. Basically I'm not sure if I need a throttle return spring, or if there's a way to tighten the springs already on the carb, etc. Also, I'm not sure if the bracket thing that connects to the accelerator linkage is positioned correctly. The linkage just has a loop that I put over this post but there's nothing to hold it down so I'll be looking to add something there.

I swapped out the same exact carburetor I had for a new one so I thought it would be more straightforward but I'm stuck atm so any help is appreciated, thanks.
