Hi,
First thing to try is separating the engine from the frame and rechecking the ignition. This is done by unplugging the wire (usually yellow or white) just to the right rear of the airbox.
If there is still no fire, then it is probably the armature. Replace and gap at 0.010-0.014" and a business card will make a makeshift gauge to do this.
Peace,
Clarke
