Just finished rebuilding all three carbs on a '98 Mercury Factory Jet 60/45. The motor is actually a 60EO. The carbs have a threaded opening just to the left of the idle adjustment at top right.
There were no plugs in any of the carbs, but the rebuild kits contained threaded plugs that fit the openings perfectly. The opening enters into a small chamber on top of the carb. In this chamber there is an open passageway leading to the top of the float chamber and float bowl. It seems to me that an opening like this would be a good place for dirt and other foreign particles to get into the carbs. The carbs were pretty dirty inside the float bowl and one of the main fuel jets was almost completely stopped up. My question is this; anyone know if these carbs are actually designed like this or if there were plugs in the carbs at one time and they were removed for some reason?
