I have a 1995 120 hp Force. The idle was not smooth and too high so I took out the idle mixtures screws and sprayed in carb cleaner. I think the problem is a bad gasket in one of the float bowls and it was sucking air and will find this out when the gasket arrives. Question:... Does anyone know how many turns I back the idle mixtures screws out to get back to "factory" setting?
