I have not had any luck getting the engine to start. I ride it down my street and pop the clutch. and nothing. The fuel line is open. I primed it. Choke half way. Then all of a sudden after about ten time doing this, over a couple of days the chain starts giving me problems. Popped off then I read adjusted the chain and tensioner. Then today the chain locked up. It will not move with the clutch in.
