I have built a go kart frame that is around 300lbs and I have a 389cc engine. I'm looking to go both on off-roading at my cottage and on roads at home. I don't know if I should us a centrifugal clutch or a torque converter? If ether one what should I get because my budget is 300$. I also live in Ontario Canada so shipping from the US is expensive so anything from Canada would be better.
