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.

I don't even have the throttle cable, my car has a factory cable, hooked up. I'm in the motor compartment starting it with a jumper off the harness I made actuating the throttle by hand. It's not going any further forward. The blades and throttle lever are in the same position on and off the intake. Idle set screw is backed out entirely
