We’re new to the karting game. Bought a 17 model charger with a roof Miller motor. My ?is we’re running purple and blue plate. What jets to run in the carb? The carb runs real rich when idle but give it gas it clears up. And the clutch is a bully when should it come in? It’s around 3400 now. And how does Birthday works. My son will be 12 in February it says 10-12 purple and 12-15 blue. He never raced before
