    Carb identification

    Hey guys I need some help identifying these carbs I've recently purchased for my seadoo 720 it's a 46mm mikuni annular discharge type carb with what looks like a mid range jet that has been drilled and added into, I'm running them with 2 internal fuel pumps until I get an external one I'm having a hell of a time getting these things to work at all

    I have a factory pipe ve head and an r&d intake with open f/a I'm curious if anyone has any experience with these carbs before thanks for any help guys

    it's an SRE. Similar to a blackjack except a mid 3rd circuit jet has been added.

    Just leave the third jet and change the highs and lows as needed. What kind of pipe are you going to run?
