Re: Engine Still Won't Start :((
#1 don't worry about it.
#2 the spark plug wire threads onto a tiny screw in the CDI. just turn it clockwise while pushing it in. you'll feel it go on, and when it gets tight, stop.
#3 if you get your motor to start, it won't run for long because of this. serious damage will occur, if it hasn't already. serious as in, you need a new motor.
an exhaust leak like that will create dangerously high temps, and your motor WILL seize.
