How to Rebuild Your Carburetor - Write Up
I have to say i was a little intimidated by all the litte complex workings and intricate system of parts, but once i got in there it really wasnt that bad, it was actually quite simple and easy.
I'll start with a parts and tools list
Parts/Supplies:
-Carb rebuild kit
-A few cans of carb cleaner
-Bucket of solvent to soak parts in
-Lots of rags
Tools:
-Lots of screwdrivers preferably a bit driver with an assortment of bits as well
-Sockets and open end wrenches
-Needle nose pliers
-Assortment of brushes
To start things off go here and download the fsm.

This is for 84 and 85's you may have to searh a bit for earlier fsm's.
Print off the carburetor section (Pg. 246-270)
It will tell you how to do a complete teardown, inspection, assembly, and tuning. By far the best helper you will have during the rebuild.
Mark your vacuum lines well if you dont know the vacuum system.
Before you start in i should tell you that most jets and screws in the carb are soft and fragile, make sure you dont strip anything out (its easy to do)
I put the carb in the top of a bondo can to catch all of the crap and carb cleaner that came off so i could keep a clean work surface, then you can just dump it out periodically
I found it helpful to take pictures of how stuff comes apart JUST in case.

Take pics of the jets as they come out, some of them look very alike
Make sure she's all nice and purdy
Best way to do it is to soak the jets and screws in solvent overnight they come out in amazing shape
And do the step by step reassembly in the fsm and youl be good to go.
I am blown away by the improvement its way more responsive, idles way better, runs better on warmup, and should get better gas mileage (havent checked yet) overall it has a brand new, real clean feel its like a whole new truck.

NICE write up!
I have been debating on doing my friends 85 carb. Looks pretty straightforward.
Do you have a link to the carb kit you bought???
thanks

The carb comes apart in three sections, as long as you pay attention it's actually not very hard to do at all. I had the oppertunity to have the help of my auto teacher after school freshman year.
I was contemplating on doing a writeup on this same topic, now I don't have to
Just curious, did you take the plug out so you can adjust the air/fuel mixture?

how to replace check balls
I think I'm in trouble here. Couldn't find a way to remove check balls from the auxiliary accelerator pump on this same carb from an 85 22R. They are visible through the holes in the diaphram areas of the AP and AAP sides, but there is no obvious way to remove them.
In trying to push the brass piece up through the hollow on the auxiliary pump side of the carb through the hole where the ball is visible, the end of the brass tube that I think the ball seats against broke off, and I still don't have a way to remove anything.
In hours of extensive searching, I can't find anything regarding how to replace these check balls, despite the carb rebuild kits having them included. Does everyone ignore these?

Did you actually break off the end of that little brass tube inside the hole before you ignored them? I sure wish I did!
Nice build, by the way--but didn't see anything referring to engine work--but man that's a cool engine paint job!

Nope, i just didnt bother. They moved freely and from what i could see they looked fine.
Thanks, its been a long project. Yeah, the engine rebuild happened before i even knew of this site, gotta dig up some old photos.

I didn't replace the check balls, either.
DON'T GET RID OF THEM, they are perfect (well, one of them is) replacements for the ones we all lose when we rebuild our manual hubs.
