This just started out of now where so it has me comfused. its been running fine with no problems and it was even fine today in the morning. But today a little after lunch time some friends and decided to go riding. we got there and it turned on fine i ripped down the drive way once and about half way back up it started to backfire a little while i had the throttle in then it just spittered and sparterd and would not rev at all and it aventualy choked itself off. well i then took the spark plug off and checked it and it had spark so i put it back in and tried kicking it over and if fired up and idled rough and when i would rev it up it would just spitter and spater again and choked itself off again then i would try to kick it and it wouldnt even turn on any more what do you guys think this could be?
