Try replacing the magneto first. It doesn't look like there's anything wrong with it but replace it anyway. It is the most likely cause if you're sure you put this thing together correctly.
Not too smart. It's rarely the reason motor won't start 1st time. Usually it's because rider gives up too soon
. Check float bowl for gas, check plug for spark, and go down a big hill first time wiggling the throttle.
And replacing without testing ain't that great an idea. Check magneto coil with a meter. They only cost $2-$3 and takes less than a minute.
