I just bought a usted Macbook Air. Its only a couple of weeks old but i still feel i want to do a complete system re-install.

How do i do this withouth access to a disc?
 
hm i just did a complete recovery, i downloaded lion and installed it, but everything looks the same, all the settings from the old user is still there.

How can i make it so its like when you buy it brand new?

OK u suppose to...

(1) Download but NOT install.

(2) U create a bootable external HD or flash with the installer in it and boot from that.

(3) U then use disk utility to ERASE your internal HD. That cleans it up.

(4) THEN you run the installer.
 
You would have to erase your drive and reinstall the operating system fresh. You can do it through disk utility.

Mrbobb beat me to it. ^

It sounds like you just reinstalled without formatting the drive. Do this.

Hold command-r when booting to get to the Recovery HD partition. Once that loads start Disk Utility and select Macintosh HD on the left then erase the partition. Then quit Disk Util and proceed with the install. It will take a bit as the OS will need to DLL from Apple's servers.

This will give you a fresh install like out of the box.
