This is a link to the Traxxas website. Obviously it's not your engine so the settings won't be the same but most nitro engines are similar and it will give you the general idea of what and where the needles are.

Also, if you don't have tuning experience - I assume you do not - this is a good link for the tuning procedure. Again, not your motor but the procedure is the same.
