Can't find pilot screws in these Mikuni carburetors

    Hey guys, as title says, I have no idea where I can find pilot screws in these. They come from '97 XJ600 Diversion but I don't know what carb model that is. Isn't it like that the elements I marked in the last picture are the pilot screw plugs? Any help would be appreciated.

    And by the way, the problem with the bike is that without choke, cylinder #3 doesn't fire and with choke cylinder #4 doesn't fire. I guess the only reasonable answer to that is in pilot screw adjustment, as cyl #3 is getting too lean mixture and cyl #4 probably a little bit too rich one, right? TIA

    The circled areas look like plugs to me. Are they like rubber? If so they might be replacement plugs.

    Yep, that's them.
    Pilot mixture screws lie underneath.

    Lucky to have the plugs. I had to make some for my carbs.

    I have yet to encounter any plugs on a Canadian model.
