Re: carb tuning.

Looking down from above....Turn the jet adjusting nuts counterclockwise until 
they stop. Then turn them ftwo full turns ( 12 flats ) clockwise. That will 
get you to a good starting point. In order to richen the mixture continue to 
turn them clockwise ( dropping the jet relative to the needle ), and to lean 
the 
mixture turn them counterclockwise ( raising the jet relative to the needle ).
