I never fire up a new engine without opening it up and cleaning the internals first. I don't care how much fuel you are flushing through an engine- if there is really any metal fragments in there before you start it up you will damage the engine. It only takes 10 minutes to open the engine and clean it with some denatured alcohol or old fuel and compressed air.
