I got it running after doing alittle bit of carb work. Ran for about 20 minutes before cutting itself off. And would not restart. I found I had no voltage coming from the stator and replaced it. After replacing that and the timer. There is no fire still. I have good power going to the cdi box but none coming out the cdi box going to the coils. What could be the cause or issues. I have checked all grounds too and the kill switch is unhooked
