Now we are getting somewhere...
I have a '73 CJ-5 with factory V-8 also.
I'll have a look...
1. This is a clean air vent.
It's intended purpose was to supply clean (and cold) air for the choke regulator.
If it's not hooked up properly with NEW hose, cap it like in the picture.
2. Choke regulator.
Adjust as necessary, instructions on the end of the canister.
Ford had a bad habit of the end of the bi-metal spring slipping off the choke flap arm, so you may want to check that.
3. Ported Vacuum.
This is the vacuum port that's supposed to supply your distributor.
Make sure it has NEW hose or is capped.
4. Idle adjustment screw.
Take the screw out, make sure it has a point on it.
If it doesn't, you are in for a rebuild and new screws, if it does, squirt some carb cleaner in the hole and see if it drains quickly.
Cleaner with the little plastic straw works well here so you can really get down in the hole.
If it drains and the screw has still got a point, replace the screw, GENTLY screw in all the way until it bottoms out, then back out 1-1/2 turns for an adjustment starting point.
5. This will be the large manifold vacuum port.
NEW HOSE to where ever it's going... PCV or brake booster, ect.
6. Factory ID tag.
If you have one of these, the carb probably hasn't been opened, or the guy that did it actually knew what he was doing.
This is the little bugger that will get you the correct parts.
If you ever buy a used carb, look for this tag, and look to see if it looks like it belongs there...
(IE: grease smudged where it mounts, rubs from vibration on the zinc carb bowl parts, ect.)
4. Idle Adjustment Screw.
This one is out of sight under the float bowl.
Same drill as above for this screw.
6. Factory ID Tag Again.
7. Accelerator Pump Housing.
8. Small Manifold Vacuum Port.
Make sure this is plugged with a NEW hose or a NEW cap.
this can not be left open.
9. Not shown, New base plate gasket...
You must not allow any leaks at the base plate of the carb.
Don't over tighten the bolts or you will warp the baseplate of the carb and leaks will happen!
