I have a code 2-2 coming on in my 2001, 115 Hp 4 stroke Suzuki , we have changed out many parts to try to find the problem with no resolve, items changed , computer , throttle body , map sensor , air valve , plugs , valves adjusted , timing checked. compression checked , leak down test , the only way the motor will stay running is to adjust out the air mixture screw on the throttle body.

Did you use a factory service manual to properly diagnose all those parts as failed, or did you just throw them at the engine hoping one was bad? That's a lot of expensive parts to just be guessing. Some of them have nothing to do with a 2-2 code.

That is not a mixture screw - it is a bypass screw - did you put the IAC in fixed duty cycle to properly adjust it?
