1983 toyota Tercel Revs up and down at idle

I managed to get an 83 toyota tercel 5 door, and i am stumped by a problem we uncovered. at first the idle was set high and untill the engine would warm up unless you kept down on the gas it would idle for a few and die. once the engine heated up it would idle high, but stay there. we re-ajusted the idle according to the factory but now on start it revs up and down and i am stumped. Im not incredibly inclined with this kind of mechanical genius, and the few freinds i have that have any inclination are stuck. soo im just kinda asking for someone to point me in a direction to start looking, because there is no smokeing and all the vacum lines look brand new.

I did that, and nothing, I checked the bolts on the carb and they were a little loose soo i replaced the base gasket, and that helped a little bit, but now while the engine is cold it is fine, as it warms up it gets a little worse and worse and the only adjustments that help it make the engine idle high.

Lets try this-spray some carb cleaner on the carb choke plate-adjust it for initial opening and the fast idle cam @ 2nd highest spot @ 1200rpm.
