Sounds like recoil spring to me.

No, just tells you which cover to take off and start investigating is all.

One has said it and I will also. My cs590 has made that noise since day one. I brought it home and I could hear it. Figured it's got a five year warranty so it something goes then it goes. Never had one issue and still making that noise.

Sounds like one of the recoil pawls is hitting the flywheel or rope pulley
There is going to be a worn spot somewhere that will indicate where it is making contact.
I have a CS590 that makes this sound as well. I've had the saw for two years, I believe that the noise started within the first year of use.
I also have a CS 7310 that has "maybe" 8 tanks of fuel through it. It just recently started making this noise as well but it is a little more pronounced (louder) than that of the 590. I swear that the saw "jumped" a little as it was sitting on the ground idling. That is a little concerning to me.
I haven't dug into either of the saws. I always assumed that it was the oiler chirping but I am not overly familiar with all the internal workings (fairly new to cutting ALL the time to feed an OWB that is undersized for our house
)
I bought the 590 at a local Home Depot so no service options there really. The 7310 I bought from a local dealer so I might take it in later today to see if they have heard this noise in the past. If I find anything out I'll update here.

Well, I didn't take either of the saws into the shop but I did send them an email describing the noise.
According to the tech, it is the clutch partially engaging and slipping in the drum due to a high idle speed. He said that they have seen this before and lowering the idle speed takes care of the "chirping" noise.
Hope it helps

Hey Richard,
I currently have the same timber wolf saw making that exact “gasping for air sound”. I’ve had the saw for a year and it just recently started: did you ever figure out what is was?
Lower the idle speed, sounds like the clutch is just on the point of engaging
Try greasing the sprocket bearing inside the clutch drum

Apolicies to prop-up an old thread. Good info here on the idle "chirp". HuskIhl nailed it. Maybe help someone else.
My Husqvarna 55 out of seasonal storage exhibited an Idle Chirp. Or gasping for air noise as description. Bit like a metallic'ish belt whine. But very intermittent & idle only. Lower idle speed reduced frequency but did not eliminate.
Checked Recoil Pawls, Clutch Spring, muffler baffle, then noticed confirming issue starting saw without Bar & Chain. Shutting off saw, I grabbed clutch drum to stop spining. It makes the noise when bearing scroll up to speed. Restart, it repeats. Yep, was a dry clutch bearing.

Spray a little penetrating oil all over the clutch side and if it does not quit spray on the flywheel side. That does not sound like a bearing or something major.
