  • Identify Carb Parts

    While working on my carbs in the front room, as I was in the bathroom my pussycat decided to jump up on the table and help me. Anyone need a bow for a violin?

    Anyhow, the brass plug that the carb needle goes into is missing, I know its somewhere in the house but pussycat won't tell me where he swatted it to.

    I look at the parts fiche but am having trouble identifying that specific part. Is it the main jet? Am still a newbie when it comes to carbs (but learning).

    Thanks

    Jack, I think you need the "emulsion tube". I do have spare '78 and '79 carbs here. My beast died, so I can't make it back up to your place, and the "Daily Ride" is in parts, for a tranny fix. If you have any reason to get down my way, you can have what you need to get the carbs back together.

      Jack, I was just thinking, it may be the main jet you cat played with. Send a PM or give me a call on the cell, 831-234-8721. I'll be outside working on a transmission.

        Jack,

        If you go to the link below at dansmc.com (great site for home mc mechanic, BTW) you will see an exploded view of a Mikuni BS11 carb.

        Part #17 is the main jet, which looks like a small plug, with a little hole in it. Part #18 is the brass washer that goes with it.

        Part #6 is the main nozzle, a.k.a. emulsion tube. It is a tube, about 2" long, into which the needle on the slide goes.

        Hope this helps.

          "Mining for brass"

          Rack and screen the cat's litter box carefully tomorrow. One never knows.
