    Plastic baffle around the main carb jet?

    I have an 85 250sx that I am rebuilding the Carb. I took the carb apart and I notice that it didn’t have the little plastic baffle around the main jet. Is this needed for me to properly tune the motor or can I do with out it?? Thanks!!

    Its called a "Swirl cap or cup". It just helps focus the main jets fuel supply from the bowl and its not really needed. Its good for helping out at WOT, over bouncy, rough terrain where the fuel in the bowl can slosh around.
