I don't think your supposed to adjust that without a gas analyzer? I used to mess around with mine when I had one and it didn't seem to make any difference so it must be a minor adjustment for emissions. It only changes the mixture at idle.

Big difference at idle or through the rev range?

I heard from somewhere else that it only affects idle which doesn't really make any sense to me, might have to investigate when i finally get the car on the dyno.
Sorry for Hi-jacking, I don't think theres much you can do typer unless you get hold of a adjuster with a screw in it.

Has the hole perhaps been plugged up so noone could adjust it?
As the screw sits recessed about 6mm on a mixture adjuster (on mine) and that one pictured looks like its almost flush.
