I would recommend charging your batteries fully. Then try that. If that does not work then check your wires to see if one of them is not fraid or broken.

If you are running the stock dle ignition test your engine with a known good ignition. Those ignitions sometimes fail.

Make sure that your spark plug has got a good seal.

Also make sure that your choke is not obstructing any airflow. If your choke is half or somewhat engaged then it will suck more fuel.

Try those first most likely batteries or ignition going bad.
