I just got my carb back from Jim C and am ready to slap it back on. When I took it off there was no gasket to be seen (except the one that looks like it is molded onto the insulator). Do I need another gasket?
I managed to get a good seal without adding another gasket. The insulator has a gasket on the surface that conformed to your carb a long time ago. If you were to change carbs, You might have a problem getting the two surfaces to mate well. Reusing the orgininal carb should be ok. I did choose to shave down the swolen bump on the gasket that lined up with the counterbored bolt hole in the center of the carb - probably not necessary though.
