SOLVED! 318 2500-3000 rpm idling issue. Don't think its a regular vacuum leak. Swapped 2 intakes, 2 carbs ,and 6 different gaskets still no luck.

Also hey since the core issue has been solved can I mark this post as solved? If now we're just discussing tuning it maybe I should make another thread when I get the car driving for actual load data.
Not a bad idea.
