It would be in an OMC factory service manual for your motor because every motor is different.

Ok i don't have manual but I have a idea from reading on here with motor off I shift it to forward and open trottle wide open and I adjusted butterfly in right position (flat) now when I trottle back down my lil wheel that touches the trottle cam (guess that's what it's called) how do I adjust this to touch, cause I lossen the screw for it to touch it messes up my butterfly again...any help with that

You could try adjusting it so the roller is even with the mark and is barely touching it but not moving the butterfly shaft. Try that but it is best to get a manual for your motor.

You can try at Boatinfo the library. On page 2-66 of the 2-70hp from 1990-2001 manual. It explains how to adjust the throttle plate. Take a look and I hope this helps. It is too much to type out .
