the carbon around the thread doesn't tell you much. it quite normal to have bulid up there. what you really want to look at is the tip.

 

i can't make up much as the 2 photos look conflicting? the 1st photo look slightly off-white while the 2nd photo look slightly drak?

 

guts feeling telling me it is slightly on the lean side.

Dont change a thing.

Brown hints on the second pics shows that you are running well.
