Yd100 starting issue

I'm new to these 2 strokes as well, but could a weak spark be caused by too little of air gap on the magneto armature?
 
Or possibly the magnet flipped over backwards causing weak spark, just throwing some ideas out there.
 
Possibly posting some pics of how your motor, carbie and your electrical is set up might be of help...you would be surprised how many times that all we had to do here was just see a pic and something jumps right out at us that needs correcting...Members here have solved many a problem this way...DAMIEN
