OK here is the second Kart I picked up the other day. It was thrown in free as part of the "For Ton" kart I bought for $150. Two karts for $150 is not something I could refuse even though both are non running. Anyway, this one is Rupp he said. I know next to nothing about karts so any info on year/model let me know. Crazy looking engine that says Craftsman. I had thought it was a Briggs at first glace... Any way I can find out more about it with the numbers below? Also what's with the sproket in the middle of the axel like that?
