    Here’s the carb I won on ebay to put in my 1969FJ40. It looks almost identical to the one I have except for a couple of things. Can any of you who know about carbs tell me what these lettered items are that are not on my current carb? What is ‘a’ some sort of check valve like a pcv valve or something? There’s a wire ‘b’ screwed to the carb body. What’s it for? Where is the other end supposed to go? Is it for grounding the carb? What is ‘c’? Looks like some air tubing goes on the end of the thing. My current carb doesn’t have this. What dod I do with it? Thanks guys.

    Go look at the SOR web pages to see more pictures of this rare
    carb. As far as I can tell, it was only used from 3/69 to 9/69.

    It would be great if we could get Jim C(henoweth) to tell us what
    this carb was about. I wonder what kind of air cleaner goes on this
    carb? Most early Aisins did not have a center stud like this one does.

    I have the exact same one which makes sense because mine is a 4/69'. So I will also look forward to any info.

    The thing with the wires is the idle solenoid. Needs a 12v hot lead to it when the ignition is on. The "C" is the "pulloff", needs to be connected to the vacuum nipple at the base of the carb, or as I have done, you can run without it.
    That is a weird looking carb. Is it a 1bbl?

    I'll post some other picts of it tomorrow, the rest of the photos are on a computer at home. The carb has two openings on the bottom one large one on the top. So I'm not sure if that makes it a single barrel or a two barrel

    Looks like a 2bbl, now that I look at it. It is waaay different.

    Degnol, this is a stupid question, but what is a ''pulloff''. I have something like this on my 71 carb, but the is no vacuum line on it. Should I put one ???

    Thanks :beer:

    Well, as I said, I ran without one even installed and no problems. If I am correct in my assumption, it pulls you off the fast idle that works with the choke. On my old BMW 3.0CS, they referred to them as "Choke pulloffs". I used to hear them called "pots". It may also cushion a sudden deaccelleration when you take your foot off the gas. I never noticed any difference running w/o the thing. I think the po neutered it because there was only one vacuum port on the carb and it was needed for the vac advance distributor. Currently, I have a carb on it that has the pulloff, one vacuum port, but I just added a "t" fitting and run both off the one port. Dunno if it will work, because I Fupped the alt wiring and it is d-e-d. I;ll fix it on Sat, Poser fixed me up with a wiring diagram I can read!
    I'm a rube so may not be correct, but that's what I think.

    This is definitely the rare two barrel which only come on the
    cruiser from 3/69 to 9/69. You guys that have one, what
    does your airfilter look like? Post a PIC!

    I believe that the choke pulloff works by using vacuum to
    circumvent the choke if the engine bogs down by being
    "overchoked".

    Funny but that wire looks like it goes directly to the body of
    the carb and not to the idle thingy.

    Interesting. A totally unique air cleaner housing to go with that
    totally unique carb. I note that you have the center hold down
    bolt blocked off with some blue tape. Don't let that blue tape
    get sucked down into the carb! Someone who is active on the
    LCML should post a teaser to see if Jim C. will give us a story
    about that carb. My late '68 just missed having one (I have
    the 1 BBL instead).

    My 69 has the same carb. Nice, I have the bastard child of cruiser carbs! I keep looking to find a rebuild kit for it but it always seems to be skiped. Can anyone point me toward one. Thanks for posting this, I am always finding something new and interesting.
