Wanted info on Mikuni carb parts on a jlo

[Supervw1]

need help identifying the carb and a part thats broke. this was on a 74 wildwolf 295 I just got.

That fitting allows fuel from the main jet to flow up into the venturi. I think the only sizes you'll find them used with are the 26 and 28mm round slide. I'll see if I have any.

Thanks , I have messed with bikes alot over the years but this style is the first I seen like this. normally I see the main Jet screwed into this spot .
