    Mikuni BS32 parts go?

    OK, I have a pair of BS32's sitting on the bench that I have taken the jets, slides, float bowl fuel inlet needle assembly and choke plunger assembly out of. The carb bodies were sitting on my bench and when I picked them up, laying on the bench underneath where they were sitting was a small spring about 1/8" diameter x 3/8" long and a steel ball that is about 1/16" diameter.

    On the parts fiche, these two parts are #59 and #60. Unfortunately, the fiche resolution is not clear enough that I can see where exactly they go.
    There is nothing on the side of the carb the arrow seems to point to. I am guessing maybe part of the choke plunger assembly? Anyone?

    I seem to remember a setup like this on my old Yamaha. The spring and ball are for the choke plunger bar detents? IIRC it was a real pain trying to get them back in there.

      I think you may have it. The diagram arrows to the choke plunger bar area and the bike is a 1979 XS400. At least I have an idea what to look for and where now. I'll take a lookie see. Thank you very much.

      Edit: Just went out to the shop and checked the plunger bar and the detents are plain as day. Ya nailed it. Thanks again.
