Started with a Mac 91 (1978), then a Mac 91A. Also drove a K88, Open Mac 91 and an Open Mac 101 (an absolute Rocket). Ran everything Sprint, Dirt, and Laydowns and Sprints on RR tracks. Left karting in 1984. Got back into karting in 2011 with a PRD running TAG and open 125, tried sprints (not my cup of tea to old and fat), but RR only now and love it.
