So i've been examining my carb and some things dont look right. First of all it dont look like the secondary flap ever opens. I was told that its vacuum controlled. I want to know why its not opening.
There are some vacuum lines that are plugged up..one on the front and two on the right side of the carb. One's for the egr but and dont know where they're supposed to go so if anyone know plz lemme know.
Another thing is that the linkages on the right side of the carb seem really loose. Am pretty sure they aint supposed to be like that.
Lastly i have no kickdown. I need to know how to adjust the detent cable so if anyone can gimme some pointers it'll be really appreciated. That's all for now.

Here's some pics of my carb...
