I am trying to get my motor running right. I don't know where the air adjustment screw should be set on this motor. Model C25ELRS 25hp Yamaha<br /><br />Any help appreciated.

Around 1 1/4 turns from a soft stop.

SOFT STOP ...... very important words, don't break it off like I did ... don't work on an engine after a rough party the night before ...
