My only other concern is if it will catch the high idle like it is supposed to once i replace the cap. Right now it will only catch the first notch, wich isnt enough to keep it running always.
I've just never had to fix a choke before ... everything i've ever owned just worked right....
The hot air tube goes inside the manifold; see 5th pic. I'll link a write-up fmc400 did and you can see it in the pictures. It's for a 2brl but is similar. Great write-up! He's a major contributor to this site and his knowledge is un-surpassed!

If you don't use the hot air stuff, you will need to find the external tubes, then you can use a 12v cap like I linked to in my first post. Other wise if you return it to factory you can use this one:

During the adjustment process you will put the choke cam on the proper step and there is a screw you will turn to bring the fast idle up to spec. Not hard to do.
I have been looking for an "on-line" rebuild instructions or pdf file for you but haven't found one yet. My '79 manual is a hard copy and harder to upload.....
