I have a 1989 sun tracker pontoon boat with the 90hp Johnson that I cannot get to run it'll spin over fine. I have spark. I rebuilt the carbs, fuel pump, and installed a new ignition switch and spark plugs and wires a fuel tank and primer bulb and line. I'm not sure if I'm using right cranking procedure or not as this is my first outboard engine. But I know if I unhook fuel line from the pump it barely pushes any fuel out of the line while I pump it. And I can spray a little fuel in the carbs and it'll act like it wants to start up. Any help would be greatly appreciated
