Vacuum leak?

Hey, Scot here. I saw something in a post talking about vacuum lines and PCV connectors with a guy and an 83 Jeep w/ a 258. IHA 74 CJ5 w/AMC 232. I just redid the wiring harness w/ a Painless kit. Everything is working fine except the engine sounds like its missing or something at idle. I have plenty of power while driving. Itís doesn't hesitate when shifting. Just slightly rough idle. All the original smog stuff is gone except a PCV solenoid on top of the engine and the EGR valve on the manifold. I keep being told this may be a vacuum leak but no ideas how to resolve the problem. The carb has about two ports that had hoses at one time but no longer. Covering them does nothing.

Any ideas?

I have a similar problem. Here's a bump for ya. I'm a bit curious about this too. I assumed I had a vacuum leak or maybe my carb needs a rebuild (which I can tell it definitely needs one).
