Looking at this drawing, the choke and the fast idle screw is what you will be looking for. it may be a phillips head screw, but it also may be a torx head screw. I cant remember if it's a T15 or a T20 torx. The choke triggers the fast idle.
The engine has to be cold when you set it. With the carb in front of you, press the throttle down and let go. The choke plate on top should close shut. If it is not fully closed, then that has to be adjusted first.
The choke in your car is not the electric one, but it is adjusted the sam way. The Olds choke is just as good as the electric one. But it has a plastic cover that is brittle, so be careful not to hit it. It has a big flat slot for a screwdriver to turn the cover for adjustment. First you must loosen the 3 hold down bolts locking the cover in place. You can see the 3 screws in the drawing on the choke assembly. one is down, and the other two are up at the corners. The screws are in the same spot on your carb. Loosen them til you can turn the cover by finger. Do not take them out!!! Turn the cover to close the choke plate on top of the carb. then give it a bit more to put tension on the plate. Then tighten one of the screws. Press the choke plate in to test the tension. It should snap back quickly, not too hard, but kinda hard. When you get that kind of tension, tighten up the 3 locking screws.
While the engine is cold the choke is tightly closed. Allowing the engine to start without pressing the gas pedal. Note: if your choke was not closed when the engine is cold, you would have to pump the gas pedal several times to get it to start.
