Quadrajet Issues

Hello everyone this is my first post here on the forum and I have several questions about a quadrajet carb. I have a '79 chevy with a 350 in it. With a 4 bbl carb ontop of it. The engine has been sitting for years without being started. I threw in a rebuild kit for the carb and got it back on. The process to get the engine running wasn't hard.

My questions:
1. The choke lever is always stuck, when I hit the gas the lever sticks into a position and does not lower. The only time it lowers is when you tap the gas really quick, or manually pull down the lever. The lever never goes down because of the bog. Is this normal?

2. When I tap the gas slowly, it runs fine. In the upper RPMs it begins to bog and pop. If it's in drive it will bog down, if you keep on the throttle it will just stall out. What are the possible causes to this?

3. When you hit the pedal it just bogs down for a second, then kicks in. I tried messing with the idle and fuel screws but I'm totally new to this. Any tips on how to tune it/or any good sites to look off of?

Sorry for the questions, especially the q-jet experts.
Any tips are greatly appreciated.
-Thanks
