Usually, mixture screw turns out to enrichen (adds mixture);

And air screw turns out to lean mixture (adds air).

Good Fortune!

I'm confused (nothing new). The air screw and mixture screw are the same??

Here's comparison of air screw vs mixture screw on manual slide carbs.

With CV carbs, am thinking it would be a mixture screw.

Good Fortune!

It's a cv carb so the pilot system is different.
