vacuum diagram trouble

[firejunkie]

hey everyone I'm new here, I have a 81 CJ7 AMC 304 4spd standard, I've recently swapped my engine because I over revved the old one, floated a valve and ended up with a giant hole in #2 piston. that being said I replaced it with a AMC 304 from the junkyard, it runs and idles but backfires at idle, I think I screwed something up when attaching the vacuum lines. the engine has a edelbrock intake and 4brl carb non egr. I can't find a diagram anywhere, even the stock diagram would be helpful.

Thanks,
sorry if this has been posted already
