ive messed with the idle screw and the air misture screw no matter witch way you turn them, all the way in, or all the way out, it still runs away the only thing that kind of helped a lil was when i fully choked it all the way out but still running way to high. im just gonna leak down test it and go from there. one i leak down test it and it dont have any leaks where will i need to look next.
