Yes, you need to tell us what type of help you need reference to your engine. What "set-up" help are your requiring?

High Speed needle-valve:
exactly two turns open from the fully closed
position.(Note: If a different muffler is used, this
setting may require readjustment)

Idle Mixture Control Screw:
at basic position when the engine leaves the
factory.

Medium Speed needle-valve:
exactly two turn open from the fully closed position.

this here is a link to the manual read it

Or you can try closing the mid needle and opening up the high approximately 1 1/2 turns.
