Probably unrelated to my previous post... Ok..1995 150hp Ocean Runner

Service manual says 3 turns out as starting point for idle adjustment screw...previous owner had 9 turn out on all carbs!

I can get the motor to run on 6 turns out where it is now but this begs the obvious question..why? What would cause my motor to only run with twice the idle adjustment turns out as per service manual.

I suspect an air leak...but pumping primer rock hard I can fine no leaking fuel. Other ideas?

Still on VRO if that makes a difference.

Re: Idle carb adjustment issue

You got the amount of turns wrong for that particular engine. The range is 3 to 5 depending on the year. Check your model number again and the service manual again.
