RE: YS 160 runs too hot in Genesis

31C is the field temp here in Trinidad. I tried another run this evening (29C) with the cowl side inlet air holes blocked as someone suggested. nil fix
I normally run these YS engines about 1/8 turn open from max RPM. Is that too lean?
Saturday I will try the 30% with a 16 1/2 X 12 prop and see what happens.
