Re: Temperature and Air Volume
Ask any pilot what he thinks about 'density altitude' and aircraft performance. As for humidity, they injected water into the carburetors of WWII fighters to raise the compression/horsepower of the engines. Google, 'water injection'
Altitude above sea level will play an important part in carb jet selection. The higher you are, the smaller the jet needs to be to compensate for the less air density.
I know this is an old thread but Maniac bumped it. I just added a little food for thought.
