    Merc 5.7 Hiccup

    I need some help from the group, I have a carbed 5.7, I recently did a bunch of maintenance because it was running like trash (carb rebuild, plugs, wires, rotor, sensor in dizzy).

    Mercruiser 350 carb

    So I took it back off and I am going to soak it again. I do have a question, the sealing washer under the center screw of the Ventura does not seem to have made it. Does anyone know if I can get a washer like this from the auto parts store.

    Mercruiser 350 carb

    It is a 2 barrel mercarb, yes I took it fully apart except for the choke housing. I could not get the housing screws out so I left that alone. I took the choke spring off and let the rest.
