In Caracas we are at 28 to 29C year round, a travel a lot to Curacao which is about 30min flight and there it's about 32C, and Trinidad is on the other end, so I'm not sure at their field temp.
My point is , if there field temp is hinger that 32C, he needs to richen the engine more and change fuel to 30%, we run YS on the rich side, and not just a bit.
