87 Evinrude 40hp Carb Diagnosis???

Removed my carbs from the motor and noticed one of the carbs throttle valves does not close all the way from the spring alone, like it should. There is a tiny gap at the top and bottom of the bore when it is closed by the spring. It takes a tiny bit of manual pressure on the throttle lever to close it fully and a bit of pressure to open it at first when at full close, like it is sticking a bit when closed. Any diagnosis? I haven’t taken the whole carb apart yet.

Loosen the screws that hold the throttle plates and reseat them. Do this when the plates are closed.
