Carbs and weather.

Since its getting cooler out I want to confirm.


When the air is cooler do u you richer or leaner? I figured richer cause the air is more dense so you need more fuel....

I know when its humid you can run leaner. What bout a dry heat?
Anyone want to confirm?

my experience shows thew opposite , cooler weather seems to condense the fuel more than the air so generally I find the idle mix needs to be leaner

Cooler air means more hp.

CP, that is an interesting observation based on what one would think an engine wants.  What I mean is, a cold engine needs to be choked to get it running, mileage improves in the summer and so forth.
How much leaner do you typically find you have to go?

1/4 turn of the mixture screws or less
