ok im having trouble with my bike, when i got it it worked fine and i ran on 25-1 to break it in. After refilling the tank with 35-1 mix and i had a hard time starting it. i fooled around with the screws and finally got it running. I let it run on the stand for 10 mins to warm it up and decided to take it out. I slowly rolled it down my drive way and when there were no cars slowly gave it throttle and went down the street. then all of a sudden in just shut off, i couldn't get it started and i thought it might be the cable. So i unscrewed it from the carb and made sure everything was right and put it back on. I pulled and pulled and finally got it started. i let it sit there for a bit, then when i gave it throttle it just died. It kept doing this every time i started it. I brought it home and unscrewed the spark plug and its black as hell. Im getting a new one tomorrow but would this be my prob or is something else wrong. please reply.
