just rebuilt carburetor and need info on how to set all the adjustments before trying to start and after starting also had a piece come off while i was taking carb off and for the life of me i can’t figure where it goes back on.

Or you could have a look at leeroysramblings.com
He has a ton of good information posted on the 9.9 omc's. Best of luck. Rick.

(Carburetor Adjustment - Single S/S Adjustable Needle Valve)
(J. Reeves)

Initial setting is: Slow speed = seat gently, then open 1-1/2 turns.

Start engine and set the rpms to where it just stays running. In segments of 1/8 turns, start to turn the S/S needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running.

Eventually you'll hit the point where the engine wants to die out or it will spit back (sounds like a mild backfire). At that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.
