Anyone on this board had any experience with Kart racing. I met a guy this morning that has three son's that race. All of them in different Briggs & Stratton classes. His racing shed is stocked with all different kinds of special kart racing oils. Most of them named FHS. He has lite, medium, heavy in all different names and colors. Even uses some as a 2-cycle mix. There are no SAE grades on any of the bottles, just lite, medium, and heavy. He could not tell me what the weights were, just what he uses each for.
Just curious.
