1990 Mercury 25HP Carb questions

[healey8390]

Does anyone know the float height and drop? And how many turns out from seated is the idle screw? Thanks in advance!!

For floats with metal hinges, turn carb upside down and bend the float's hinge for the float to sit parallel to the float's chamber edge. Needle valve seat and needle must be in excellent sate for the adjustment to work.

Happy Boating​

Initial mixture setting is 1-1/2 out from light set then fine tune. Float height is 1"
