i live in the netherlands.. and when it get's hotter, the engine simple will overheat, so we richen the mixture to keep the engine's cool....
i think the image that we all print, is rather country dependend.....
But you have to take into account Humidity......if in your area Humidity drops when temperature raises...then you must richen the mixture.
Humidity: When the percentage of humidity in the air increases, the engine draws in a lower percentage of oxygen during each revolution because the water molecules (humidity) take the place of oxygen molecules in a given volume of air. High humidity will make the air-fuel mixture richer, so you should lean the mixture. Low humidity wil make the air-fuel mixture leaner, so you should richen the mxture.
