tilostick it would help if u completed ur profile, year make engine size etc, the allen screw under the air filter is attached to the fuel distro assy . that adjust the air fuel mix. i have completely striped and taken my car down to the bare metal before and i havent seen a screw that can adjust the steering play. play in the steering is caused by bad tie rod ends, idler arm bushings, or bad gears in the gear box. like i said before try to flush out your power steering system first, thats the mostlikely cause of tight steering.
ps. dave not to be a dick about but can u post in the read first thread for the newbies to complete their profiles..thx
