Stock engine? What size wheels? (outer diameter, please)

Without knowing the tire diameter and overall wet weight of the kart and driver, I'd say the ratio you need is in the neighborhood of something to one.

It's all relitive... What have you got so far... Pics of the ride being built and the ideas you have...

300-350 pound kart weight with driver. 15" tall tires max and geared 6:1. Meaning a 12 tooth clutch and 72 tooth axle gear.

With any bigger wheels you are going to have to go to 7:1 or 8:1. A TC is better than a CC for what you are going for
