Build a baffle. As already suggested, block off the left side opening in the cowl to force the air over the cylinder. Block off everything inside the cowl so the air MUST travel over the cylinder head before it can exit the cowl. It's a bunch of work, but it ........ works.
Hi wjcalhoun,
Couldn't agree more with Rcpilot. If I were you I would block off the left hand side of the cowl first and see if that is sufficient. Alloy from soft drink cans makes easy to form and fasten baffles if you need to go down that road
.
Good Luck,
Colin
