Not much you can do in the time available. Tire pressure to sidewall maximum and grille block is about it. Unless it has bias ply tires, in which case set the tire pressure a little above factory recommended.
Vacuum or mechanical secondaries? Drive so as to not open the secondary barrels. Gas mileage probably has more to do with getting an even mixture distribution between cylinders than the overall mixture. Possibly disconnect/block the secondaries closed? Make sure the accelerator pump is set correctly and floats set for correct fuel level.
If you really want better mileage, that car is begging for a wide ratio 5 or 6 speed manual transmission.
