A search on the internet provided me with only sparse facts about the Karting World Championships. As far as I understand there was a World Championship since 1964 which was contested by Formula K karts from 1981 to 1992 and by Formula Super A karts since 1993.

Since 1988 there also was a second World Championship for Formula A karts (ex-Super 100).

I don’t know whether there is a 2004 karting World Champion or not. I don’t know either whether the Formula A WC was contested at the same events as the Formula Super A WC. And I don't know any exact dates.

Can anyone shed more light on the history of the Karting World Championships or guide me to a website with more informations?
