I have a 1994 kawasaki klx250(kick start)and all of a sudden, for some un known reason it wont start. It was starting very well a week ago and now i cant even get it to turn over.I have just pulled the carby out and blown out all the jets, and the sparkplug is very new and is sparking fine.so i dont know what is stopping it from going.any infomation or tips would be very much appreciated,THANKS.
