OK I have a merc 650 and am having some troubles. I have Great spark and recently cleaned the carbs on the motor. She just wont fire unless fuel is sprayed through the spark plug holes. WHEN IT DOES POP/RUN IT IS VERY FAINT. I was hardly ably to tell it was fireing except for being able to see the exhaust smoke. Now I am thinking timing but have no idea how to check it because I am use to the coil/point ignition in the smaller outboards.
