Greetings All! I have a 25hp Mercury 2 stroke, I do not know the year at the moment but the serial# is A187699. On the coil it reads 1985, but of course that could be the part number. Anyways I fogged the motor, Drained the lower end ect. But left the gas tank outside in the boat through the winter months. ( I know) I went out to fire the puppy up and no dice. I drained all the old fuel and replaced with fresh. I Disconnected the fuel line at the carb And depressed the bulb til I had fuel coming out. (Cleaned filter prior) It will not stay running after giving it alittle shot of starting fluid. Is it trapped air or what? This is my first outboard, I do my own wrenching on my cars
