Piperofna, most of what test005 has told you will work, but I have a different perspective. Since you have questions about running the engine, it sounds like you are a beginner. What are your plans for flying the plane? Have you arranged someone to help you learn? If you have, I suggest that you wait until you are with this person before you try to start the engine. They should know how to get it running and how to tune it. They will also be able to show you basic safety information to help you avoid getting hurt.
