Chances are, the diaphragms are old/deteriorated/stiff, but you could try turning adjustment needle closest to carb, clockwise and counterclockwise 1/4 to 1/2 turn (=/-) and see if idle improves. Usually, the easiest thing to do is replace carb.

Regarding the adjustment procedure you generally start your low and high mixture screws at one turn from seat, or slowly turn them in all the way until they bottom out and then back them out one full turn. You will adjust the high speed mixture screw at full throttle and get the median point between too rich (loads up) and too lean (dies out). You will want to do the same thing with the idle mixture screw, just adjust at idle rpm. You will also adjust the low idle mixture screw to give you a smooth transition from idle to throttle up. Once this is obtained, you adjust the third or idle speed screw low enough so the chain does not turn at idle rpm but high enough so the saw doesn't cut off. Hope this gets you going.
