check the spark strength.
Pull the spark cap off the spark plug (leave spark plug in) and hold it 30mm from the head. Crank the motor, sparks should jump to the head. If they dont, unscrew the cap and check the spark lead had proper connect. you may have to cut it get a good wire again if its bad.

If spark is strong,
Try

AS 1.5
N8RG clip2
