A centrifugal clutch is the cheapest way to drive your go kart. A torque convertor will give you far more power, but costs a lot. The centrifugal clutch works well, but only allows you to drive at one gear ratio, which is the same to say that it only has one gear.
However, for on-road use, the centrifrugal clutch is a great choice. You can generally get the kart up to around 30 MPH with a 60 tooth rear sprocket. A 72 tooth sprocket will probably top out around 20.
