I have a older 40 hp Johnson motor and it was running great. Till one day it started flooding and gas was running out of the carb. The boat would run fine till u let off and the gas would flood it out.Finally found a a new float for the boat because it wasnt working. and Started up the boat.. Boat will run but misses really bad. I went out and got new spark plugs for it and still does it? Does anyone know what could be wrong?
