Do your lights come on when you spin the engine?
all it takes to kill the spark is one wire that is grounding out where it shouldn't. Check around your kill switch.
I see you are a newbee. You did gap the points and plug and set the timng didn't you??
Is there a battery in your bike? If not disconnect the headlight now or pay $30 for a new headlight when you do get it fired up
Is the battery charged? are the connections clean?
