Just rebuilt carb's..put them back on motor, started easy. But now the motor idle's at 2000 rpm. How do I adjust this to the right rpm's. 1986 mercury 90hp inline 6 s/n a934952. Thanks for any help.

Re: Help...what to check now

When an outboard like yours is idling the throttle plates MUST be closed.--------Have you done any repairs that might affect that.----Repaired any broken pieces yourself ?--------Checked that all throttle plates are closed at idle ?
