Hey guys..... am I running rich or lean? Please tell me your thoughts....

That looks spot on.

Really? How about the very light layer of grey particle?

Looks a little lean, to me. If you do a lot of high speed, wide open throttle runs, you want to run a little richer.

You know Deluge, my LSN only have a 1 hr or 1:30 min play when adjusting the LSN. Is this normal for a OBR? Anything above that... my engine will die on idle Your thoughts?
