Default oldsmobile help

my father has a 1957 olds super 88. engine is the original rocket engine with hydramatic trans. it has a very rough idle. if i put my hand over the carb when idling,the idle sound okay,as soon as i take away my hand,it idles low and rough again. what would you suggest i should look at? the idle mixture circuit,screws?
if i raise the rpm when it idles,the engine sounds ok.
the choke on the carb has been disconnected.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
