My advice would be to send it back while you have time.

You mentioned in your original post that you would be going home soon and wanted to get it sorted before you did. Do not tear anything down or you may void your warranty.

Read the "new to gas" sticky and follow it.

If it is a dud (and there have been plenty of those sent recently) then the sooner you return it, the sooner you wil be flying it.

Reading your questions, I would guess you are a newbie. This engine is not suitable for you in its present form. Get some experienced help before you destroy something or void the warranty.
