My throttle cable stuck wide open in second, hit a tree landed on top of me. when I threw it off it landed on all four tires, hit a wood fence and got stuck. By the time I got to it to shut the fuel off (no kill switch) it was revving so high sparks were flying out from what I thought was the spark plug. I have since replaced the cable and now it runs great but, it wont idle anymore. I think I might have burned out the switch assembly on top of the carb. does anyone know what might be wrong?
