I have a rebuild kit for a carburator off a 1967 9.5 hp evinrude. When removing the aluminum plugs to clean out the ports I ran into a plastic piece close to the idle adjustment screw. Unable to remove this piece to clean out the ports, the three little holes for Idle. It will not move and I know there is some blockage behind this insert. Anyone know how to remove this insert???????????
The later version 9.5’s used them. Most likely you will destroy it getting it out….and will have to order one; as they are not included in the carb kits.
