I hav an 80 hp mercury o.b motor I started the motor it ran when I opened it up it ran good than all of the sudden it died and i can't get it started now I think it is a 1966 motor but am not sure i changed all 4 plugs put fresh fues and changed the external fuel filterand i am getting a firm prime on the ball. i am new with marine moters so i could use some sugestions. the motor wants to start but dies real quick i get a cupple uf putters out of it.
