Hi Peter,
Since youre taking pictures, any chance I could get you to e-mail me some?
After reading about your setup, I have been thinking of closing the top NACA
and using the lower starboard NACA for carb air with the under cowl air in
the same way as you described. I lowered my oil cooler so I shouldnt need
the extra air under the cowl to keep the 912S cool. Not sure how much carb
heat a severe clear VFR pilot will need, but you never know.
Thanks,
Jeff A258
