RTK: I like that idea and think that is the first thing to try. I'll use this beatup old cowl as the test-bed and if it cools the engine I will incorporate that into the new cowl as well as getting the upper baffle closer to the engine. Also I will play with the needles a bit more.

For everyone who has posted here, I really appreciate all the suggestions. Even if I did not comment on some posts, I still have taken in all suggestions to come up with a possible solution.

If anyone can think of anything else please keep the posts coming.
