whats wrong with this chain?

[LLigetfa]

The chain is looking real dirty and dull...

We still don't know if it IS dull or just LOOKS dull. Yes, the chain will run hotter with poor oiling and a hotter chain will bake on tree juice to look like that but I've never heard of poor oiling actually dulling a chain. A dull chain will run hotter too with the same baked look.

Agree on the burnt sap, also agree that the rakers may be a touch high. I cut my bar oil with auto trans fluid in cold weather. As far as oiling, I clean the bar groove when I sharpen, check oiler output etc. If that saw happens to be an MS 290 they seem to oil better with the oiler set back just slightly from full open. I like my saws to sling oil so I can see it paint a strip on a fresh cut in a few seconds. 1 tank of oil to one tank of fuel except on the 14" bar, only cause that's all the oil the little saw will put out.
