Thank you for your advice, very helpful. I know enough to be dangerous, but I am learning.

Thanks I will replace the spark plug. It was running fine but the throttle was sticking at full speed so my son was hitting the kill switch to stop, by doing this would it mess up a spark plug or anything else?

How do I fix a valve lash, if this is the problem?

I just bought one of these bikes and having same problem. I check the kill switch like you say, that is not it. I have spark. It sounds like it wants to start and there is a small bang when pulling the cord but it will not caught. do you think it is the coil?
