You may have weeping jumper fuel lines. Check around for any leaks throughout the fuel system.
Adjust the valves, but that shouldn't dramatically lower mpg.
Anytime you purchase a 24 year old car you may want to do a fluid and filter change, oil and transmission. I'll agree with a purge too, but that's more of a performance issue.
