Issues with reman carb install

[SilveradoDude]

I still have a few outstanding issues from that reman carb.

1. The carb kicks into high idle on cold start and doesn't kick down (even when you hit the accelerator a second time) until the truck warms up.
2. The truck is idling a little high even when the truck warms up.
3. The carb is using too much gas.
4. If it is really hot outside a get just a little dieseling when I turn the truck off.
