Chainsaw Repair

My Stihl 084AV dies at idle, and I was wondering if anyone had an idea.  It starts fine, runs out fine, actually seems a bit rich at top rpm while cutting, but can't adjust the high speed needle closed more than the "0" turns reccomended.  Once it drops down to idle, it will idle a few seconds, then leans out and dies.  If I catch it while it is leaning out, I can get it revved up again, and keep it going, but as soon as I let it drop down to idle, I've got about 4 seconds till it dies.  The low speed jet does not seem to help any, as I've opened it way up, and it still does the same thing.  I've pulled the carb, and **** it open, Tillotson HT I think, and it looked clean, nothing noticable.  Any suggestions would be appreciated, and if you have a good source for parts, I'd appreciate that.

On the 084 parts. Just post in wanted or this thread what you are needing. I used to have tons of 084 stuff put sold all the parts when I sold the 4 084's.
cut4fun and chainsawrepair is same person PM if you like also. I can pretty much find something if it is out there for sale. 

I tried opening up the throttle, but even at its stop, it still dies.  I have the high set at "0" open, and the low at about 1.5 turn open.  The carb cover says 1.25 open for low, and 0 open for high, althogh I have never come across a 0 recommended opening before.  any ideas?
thanks

I agree about the 0 turns out, but that is what it is marked on the side of the plastic filter cover.  I bought this saw a couple of years ago, and it was at 0 turns out when I bought it, and ran ok.  I will check the crank bearing, hope thats not it, but I'll check.  it is a -2 carb.  I haven't checked the tank vent, not sure where it is to be honest.
