Oy. IM is on the back side closer to valve cover. Idle speed is closer to the right side tucked in at the base of the carb. The screw seats down on a metal linkage. You can see the linkage move as you tighten the screw in.
Both the front and back adjusters were put all the way in, then backed out 2-3 turns, both pressing the metal against it.
Apologies for the novice questions. I have been working on FI engines for nearly 20 years, but this is my first endeavor into the carb world.
Appreciate your help big time. I will double check them all in the morning.
