    Bring it back to the shop where you bought it lol.

    It would help if you mentioned who made it and what model it is - many Chinese bikes are clones of other bikes and parts are common between them.

    It sounds like the starter ring gear is stripped - if you can't kick into life either then I'd suspect the gear on the crank but you say it is sparking so then it has to be turning over. Weird - did you mess with the valve clearances or anything that might have knocked the timing out? Did you use the right replacement spark plug - could it be hitting the piston crown?
