Ok guys, I need your help on this one. I have an 066 to work on here. The saw will run, but only wide open, and will not idle without feathering the throttle. I've tried adjusting the carb, but can't keep it running long enough to do so. Also I've checked for leaks, and there aren't any. What could be the cause of this?

Idle circuit in the carb is stopped up most likely. Take the idle needle out, blow carb cleaner in it and see if it comes out the little holes in the barrel on the engine side of the butterfly. Or, just rebuild or put a new one on it,
Carb issue is certainly suspect as mentioned above, but you might also check compression. I've seen saws with waning compression behave just like that; would run at WOT just fine, but won't stay idling on their own.
How did you leak check?
A leaky decomp will do that too.

Recent rebuild does not eliminate a more recent scored cyl....take nothing for granted. Have an approach and don't let "ideas" of what went wrong dissuade you. Seems to work ok in other professions....

Remove and check under both sides of carb for fine bug dust. Try turning up the LA if it stalls at idle so that you can set the low speed.
