Karting??..

Karting..
Does anybody do it? Has anybody done it? Any experience or helpful hints?
I'm looking into it...
Can't afford the shifter and the maintenance.. but for obvious reasons would be preferred LOL..
100 two stroke automatic would be fun but still lots of maintenance cost...
Lo6 (9 horsepower Briggs & Stratton class) affordable maintenance and more competitive if I was to do such a thing which I doubt...
Anyways any experience would be greatly appreciated...
