Throttle Opener Clearance, Is It Really Bad?

[Matej]

Photo while engine was fully warmed up and idle. Throttle stop screw and stop lever on TB has no clearance. But throttle opener has. Should I unscrew throttle stop screw until this 5mm opener clearance disappear?

The picture is a little blurry, but it looks like that may be the ac idle up valve. You can have someone turn the ac on, then off, and see if it moves. Is there a problem with the idle speed? I wouldn't touch it unless you are having problems with it.
