'88 4.2 carb vacuum problems

i have an '88 yj, with the 4.2, it stalls when i come to a stop, i know this is in FAQ, but that didnt help, the carb was rebuilt a few years ago, but the person who installed it mixed up some vacuum lines, i saw a thread about ripping some completely out because their just for emissions, so my question is what do i need to keep, and what can go? does anyone have any good diagrams of how the vacuum lines should go?
help would be much appreciated

Back on 2/19/07, greatdane posted a question in that regard, and somebody attached a great diagram...I am not computer literate enough to know how to attach that link, but if you'll go back, it was titled 'vacuum lines??'...or if you'll do a search on this forum, yaotta be able to find it...good luck...If you get stuck, I THINK the Haynes manual has that diagram, either post back here or PM me and I'll check

Look into cleaning out your venture tubs in the carb. Search for it and youll find some posts.

Also, look into doing the nutter bypass. You will enjoy the results.
