OK, so it got a little run time ..... handle is monumentally cooler and even at idle, lots of air is coming out diagonally down towards the outside edge of the chain cover. I dont think this cut down on any air moving past the cylinder fins, but it definately re-directed it. The last two weeks had temps between 90-100 degrees whilst today is only 87, she seems to run fine, no vapor lock or boiling fuel issues now, or before this mod. The only real difference that I can see is that the handle is way cooler and there is gobbs of air being spit out down and away from the chain cover ............ I mocked up a picture
