I just got my carb. back from the mechanic because i sent it there to get rebuilt. It is a carb. for a 1988 Johnson 6 hp and I think i have the wrong gasket on it. The carb. is leaking from a factory made indention above a screen (located on the side of the carb.). The way the top gasket is shaped, it does not seal the indention. I know this post wasnt very clear, but could someone tell me if i have the wrong gasket on it or do i have to put something in the indention to seal it.
