My 3.0 Mecruiser has a run-on problem. Someone suggested adjusting the fuel mixture screw on the carb, is that a difficult job?

Re: Run On

Has it had the problem since new? Or did it just start. You could try to richen the mixture a little bit by turning the screw counter clockwise, if it has been an ongoing problem.<br />If it just started you may want to tune it up and run some seafoam or power tune through it to remove excess carbon deposits.

Lower the idle speed if you can.<br /><br />Before you shut down let it idle for 30 seconds.<br /><br />Make sure you have the proper heat range plugs.
