I am learning slowly. I am trying to get a carb rebuild kt for my mercury 70 hp, ser # 4980610. i looked through the iboats store and orderd a kit it listed but that is not the right one. I even have a mercury part number(7212) i think. if there is any help that would be great other wise i am looking at sixty bucks fo kits. also with that there is a venturi that is no longer avail? does that meen that is not needed?
