New engine, electronic distributer, electric fuel pump ran great for about 4 hours. RPM's went high and killed. Won't start- getting fuel and spark, plugs look. Where do I start?
I'd check the timing first, spark, fuel and air is all you need, but the spark needs to be at the right time. Hopefully it's that simple, but not sure why it ran for 4 hrs then changed (if that's the issue).....
