Help, ran straight oil. Won't start.

The reason it wouldn't go is because the wrong oil was used, and likely in too low of a fuel to oil ratio. THEN the mix pools in the crankcase and keeps fouling the new proper mixture and/or plug.

Once he got it all cleaned out- boom! it runs.

I just have to ask- What is "straight oil"?
