This is my second Nova, (1st is a Flash .21 Special Factory tuned).
Tuned means tuned for higher performance in this case (ceramic bearings, more attention to crank balance and cylinder sleeve porting), and it does not mean that you can leave mixture adjustments the way that they are. With factory break-in engines; you should still run engines rich until the piston feels like its not running very tight.
Kindest regards,
