fuel goes in at connector then to fuel pump then to carbs ! remove connector off fuel line and prime fuel up so you know you got fuel ! then reconnect to engine and prime up again till you see filter filling and bulb should harden , then remove a drain screw from carb bowl and prime again and see if fuel comes out of all carb drains ! if yes then start engine with or in water with kill lanyard on if ok then good ! not then check sparks on all plugs putting them against the head for earth and crank to check ! if ok then i would remove carbs and clean the jets etc ! compressions 100psi or more on all cylinders ! less means recon pistons etc !
