I think it looks lean. If the color doesn't show up well in the pic's, I can tell you that it's a light gray and should be more of a light brown or dark tan. The plane was unloading a lot due to high air speed, I think it was running lean. I usually don't run WOT so I think that's why it showed up. Also I think possibly my fuel inlet was letting in air. I'll know next time I fly. I zip tied the fuel inlet so hopefully that makes the engine run more rich.
