Does the 660 look like it’s running lean? Muffler is whiteish

Does this 660 muffler look right or have the color of running lean?? I’m really new to this saw and only have couple runs on it milling some small pieces. Actually I lied. I cut down a walnut tree and cut about 5 rounds off it, it ran pretty good

Hard to say by that alone if its lean or not- but it looks to have certainly been hot AF.
When you got it, the muffler had not been painted in standard paint- not stove paint, or manifold paint?
Wasnt covered in sap or anything?

Pull the spark plug. It'll tell you.
