idle too high, makes undriveable

Finally got some time to figure out where the gas was leaking with the new carb, it was the new dual feed fuel line. It's a quick fuel 750 with electric choke. The carb's instructions say the fast idle speed should be around 1600rpm, which it is. But as the car warms up, it gets faster and ends up idling at 2k when I expected it to go lower once it warms up.

Drove it around the block a few times and it's nearly undriveable. With the idle so high, it's harder to control and I'm really having to mash on the brakes to keep from launching at stop signs. But then it's also misfiring if I try to floor it. Too much gas? Not enough? Do I adjust the primaries or secondaries?
Vacuum leak?
