Default RE: Engine cooling with cowl aircraft

I am running 15% and a OS #8 plug. I do have the muffler converted to a pitts style mount. With a 17x6 prop I have no trouble, and I only have one half of the cowl open like Minn said. Like others said I would look at the fuel system. Sounds like your are getting lean. Have you checked the clunk and filter?
