Im trying to buy the stuff now, is there luke a book or a breakdown that i can find, nobody wants to give me detailed info. They just want me to pay them to do it. They were kind of rude.
Sorry, racing isn't something that someone can tell you, it's a long process to learn all the ins and outs.
It actually takes a long time to learn, while they are karts, they still have almost every adjustment a full scale race car has.
I suggest find the track you plan on racing and watch, and ask questions at the track as to what kind of chassis everyone is running, type of tires, and a starting gear ratio.
All the different kart chassis setup a little different.
Kart racing takes hard work to run up front, and is a little more involved than a lot of people want to invest.
There's plenty of info here available for free, but you'll have to buy support equipment to.
Pick out your track and spend a few weekends making friends there.
When you buy, try to buy local, that way you can get some help from them.
