Changed Needle & Seat

[johnno]

Hi,<br /><br />I had a sticking needle and seat in one of the carbies in my 115HP V6 Blueband Mercury. <br /><br />After replacing the needle and seat, the carbie seems to be working fine except the motor works ok at high revs but does idle properly. Do you think I need to adjust the idle screw on this carbie and if so how should I do it?

Not sure.Look at the linkage. If it has a round plastic piece on the throttle plate,it's a Tilotsen carb, and you undo the nut that runs tru the plastic roller,turn it a little,and tighten it back up. The plastic roller is concentric,and you can make small adjustments there.

Thanks ODDD1.<br /><br />Should I adjust the idle mix or just the idle screw?<br /><br />Also should all three carbies be adjusted or just the one I changed the needle and seat on?<br /><br />Johnno...
