A little dark humor with regard to a full ride - I did it for a buddy's kid for 3 years (they paid for his pit pass and entry fee, my machinery, tires and all maintenance work and expenses, including engines and overhauls), then he graduated from karts to an INEX Legend, which they paid for themselves; I just supplied scales and maintenance and setup knowledge and help. They got quite a shock at the total monthly bills when you went all the way down to shop rags, lol. Then came the first engine rebuild..... A little experience wises people up quickly, for sure, when they're paying the bills and doing most of the work.
