Alright. Update on jeep. It idles at 800. Can hit throttle and stays running. Kind of sputters and pops. Still stalls when you stop. And thank you for the pictures. Helps a lot.

Also I notice you have one large belt. My jeep has two. One to alternator and a separate power steering belt. Though the belts seem to always flip flop ipside down and such.

Have you tried replacing the plugs wires cap and rotor. ? Also sounds like a vacuum leak. I had the same issue until I fixed my vacuum leaks and did a tube up and adjusted the timing

Mine came with factory ac so I have a serpentine belt. Everything else is the same, don't be worried about that.

I still say vacuum leak also but you are closer then before. What did you set your timing at now?

I set it at 8 BTDC like it said when doing the nutter. The plugs, wires, cap and rotor are all newish. I did find that the vacuum going to the brake booster wasn't plugged anywhere, what would the hose go to? I plugged it for now, but haven't tried driving it, as a hole broke loose in my oil pan, am going to attempt to remove and replace that on tuesday, any advice on that would be awesome as well

I had the same issues that you are having. I ended up switching to the Weber carburetor after I did the nutter bypass and everything seems to be fine now. No more stalling and it idles around 800

your brake booster line hooks to your intake. that will create a huge vacuum leak if it is not hooked up because you have a huge hole suck air around the carb. it should hook into a large fitting on the intake.

the belts flipping over means you need to check the alignment on your pulleys, if i remember right. i never had that one but i know people do get that trouble.

Could you share a picture of where the brake booster hose goes?

It's in the ones I posted. It's the big one in he shot from lower. Yours might hook into a tee by the firewall though

The big hose from the booster is hooked up. But there is a smaller hose fr there that I had just plugged. But on a recent post I saw its supposed to t off. One going to a t that goes to distributor. And the other goes somewhere I'm not sure of.

Theres the engine compartment for whoever asked me for the picture of it....
And this is the line I'm asking about that I plugged, wondering where it's supposed to actually go...

That one that you plugged is where I run my distributor and 4x4 actuator off. You have some hoses coming of the side of the carb, right? Make sure those are plugged, for now. I bet you just have a leak on a vacuum line or a small leak under the adapters under the carb. I had a few leaks in those places and just had to take the carb and adapters off and redo the gaskets and also put rtv between the adapters and the intake and between the two adapters. That finally fixed the little leaks there. Then I had to go buy about 12 feet of non fuel injection fuel line from the local auto parts place and replace my vacuum lines. That finally fixed all the leaks. Your vacuum lines will also go under to a switch on top of you t-case and from there to the actuator on your front axle and firewall. Plus, a vacuum line goes in to behind your dash board. To find out if your trouble is at your intake or at your lines, you can unhook all the little lines and plug the ports and then start the jeep. If it runs a lot better then you know it's somewhere in the distributor/4x4/dash vacuum system and then you just have to go from there.

Alright thanks. Yeah there are some small ports on back of carb I need to plug. Do I need to plug the two big ones on too of carb towards the front that use to go down to canister? I plugged it at canister and just took out the big hose that went to those

I would plug everything because something might be ported and only open when a certain amount of vacuum is hit or lost

The vauum port you have plugged in your pic is what I have to my dizzy. Also someone said check your adapter plates for leaks, I highly recommend that, that is where all my trouble was also. Sounds like the same problem you are having now.
