Hello folks I just purchased a Zodiac and it came with a retro 1967 Evinrude fisher man. kind of a neat old motor. It started right but would cut out every now and then and just die. I think the fuel must have been bad. I cleaned the fuel filter and then notice some dried cork in fuel pump so I tool it apart not knowing about the springs etc which where drop and lost. Wondering if any one knows the part number for the fuel pump kit or the whole fuel pump. As well should I mix this 50 to 1 or do these old outboards need more oil.
