Hi all,

The engine on the plane runs good and idles smooth. The problem that I have is around the engine head its starting to get blacker everytime I fly, yet I havent had any engine problems. I thought it may be getting to hot but I figured it would cut off if that was the case. So does anyone have any ideas of what could be going on. I have a 10x6 prop and run 15% cool power fuel. I dont have a tach yet so I'm not sure what RPM's its running at.

Thanks for the help.
Nick
