I have a NOS Carter WO 636SA that I will be putting on my L134 for a '48 CJ2A.
It looks clean and unused (as it should be), but with some minimal storage dust mostly on the outside. Considering this is 65+ years old and has never been used, is there anything I need to do other than strap it on and fire it up? Do I need to check anything, lube anything, clean anything, set anything?
Thanks in advance...

Your carb, if indeed NOS, should be close to what you want. The only thing to do are to screw in, but only to a LIGHT bottom, the Brass Idle Mixture Screw. Then, unscrew it 1.5 to 2 full turns. Adjust the Steel Idle Stop screw such that a very small “square” of the lowest hole (the vacuum port) in the throat is exposed. Install the carb using 30-35 LB FT of torque on the nuts to flatten the gasket. You will need to spoon feed ( a few times) some gas down the throat for the first start in order for the bowl to fill.

By the "lowest hole" (vacuum port) do you mean the one with the red arrow below, just visible below the throttle valve? There is a lower hole still, shown by the blue arrow, although I'm not sure of it's name or function.
You are correct in your identifications. Back the Idle stop screw out until the tip no longer touches the boss. The vacuum port should be, if not completely closed, then mostly closed. Inverting the carb on the bench, start turning the idle stop screw in and observe the throttle plate position changing (increasing the opening) and the vacuum port opening increasing in apparent size. What you want is a “perfect square” aperture.
Thanks Scout, I understand now. What was confusing me was that the "lowest hole" on my carb throat is not the vacuum port, it is the hole that is drilled for the idle mix adjustment screw...the vacuum port sits above that. I couldn't figure out how adjusting the idle stop screw would have any bearing on the idle mix hole, and that's because it doesn't!
This is how I have adjusted the idle stop/vacuum port now. Looks like a square to me!
m38mike: Oilly, I agree. I wish someone would put a ride together. Until then I may have to Jeep alone. Cuppa Joe please.
