Book says start with 5/8 turn out, my question is, does turning it out from there(counter clockwise) make it run richer or leaner? Any help appreciated. Thanks

it allows more of the fuel/air mix to enter.
Should stay within the factory settings .
If need to get out of them then there is a problem that needs to be addressed
