84's correct on the float level setting. It should be set so that the fuel just starts to trickle out of the sight hole with the motor running. In your case, you want to just to be able to see the fuel level at the very bottom of the sight glass. The four screws you have are the four corner idle mixture screws. Normally, with the car idling, turn them all the way in and then back them out 1/2 to 1-1/2 turns to get the idle mixture correct. I'd start at the 1/2 and adjust from there if needed. All should be adjusted the same amount. You won't see any benefit at part or WOT of different adjustments on these since they are just working with the idle circuit.
