Unfortunately there is no such thing as a factory set needle that is good for all locations, prop, altitude, temp, etc. You must tune your engine for your location and set-up.
You might not have done that much damage. Make sure the carb screen is clean and your fuel system is good, then I would run it and see. Don't forget to set the needles.

Oh, if it feels real rough and/or scratchy when turned over don't run it.
