Backing the AF screw out makes it leaner or richer?

Thanks

In most cases, if the mixture screw is on the engine side of the throttle plate/slide, turning it out enrichens the mixture. If it's on the air cleaner side of the throttle plate/slide, turning it in enrichens the mixture. Turn yours out to make it richer.

Remember to stay within the plus and minus limits indicated in the chart where you found the initial setting for the mixture screw for your particular carbs.....

IF you need to go further than that, actual jetting changes are warranted.....
