All old base stats are on the wiki via old revisions. For example, Karma was reworked in March of 2013 so you'd pick a revision of Template:Data Karma from before that date (can view them all by adding ?action=history to the end of the url or by clicking history in the dropdown beside the edit button).

http://leagueoflegends.wikia.com/wiki/Template:Data_Karma?oldid=1585806 gives you the information you're looking for. Just remember that they completely changed the way base stats work sometime after Karma's rework (no longer static increases per level) and all champions got a base armor buff to compensate for the nerf of armor runes.
