    I would like to find a cheap source of idle jets for my carbs. The
    overhaul kits each contain an idle jet but cost $15 - $20 each.
    Partsfiche.com sells the jets alone for $9.99 each plus shipping. That
    seems like too much. Can I find them for $5 each plus shipping? It is
    Honda p/n 99124-286-0351 JET, SLOW (#35) for Keihin carbs.

    Tips for cleaning idle jets would be welcome too. I soaked a used pair
    in carb cleaner, Lime Away, and Iron Out, but none of those seemed to do
    any good, and I fear that they may have done some harm.

    Not likely. I've never seen them that cheap (though I've not looked too
    hard, a deal like that would likely show up here quick enough ;-)
    Search the group's archives (e.g. Google groups search). There's LOTS of
    stuff here.


    'indiana' is a 'nolnn' and 'hoosier' is a 'solkk'. Indiana doesn't solkk.

    When I had my idle jets blocked up I soaked them in Chemtool B-12 (see
    all of krusty's posts... he likes it). Then sprayed with carb cleaner.
    Next took a toothbrush and used a single "hair" on the toothbrush to
    gently poke into the holes. The holes are small, and the inner
    diameters are sometimes even smaller. But if you hold them up and look
    straight along the jet, you should be able to see a small pinpoint.
    Using a toothbrush helps just push the dirt out, since even if the dirt
    is loose it might still clog up the hole. Be gentle when cleaning!
    It's expensive enough even when you don't have to replace ones you've
    buggered up.

    Can you see the pinhole through your idle jet? Or are they all blocked

    I'm rebuilding a 31 year old CB 125S that had not been started
    in 20 years. The gas had done something terrible to the inside of the
    carb. I DID get the jets cleaned after soaking 24 hours in carb
    cleaner then blowing them out with about 100 foot pounds of
    compressed air. My air gun has a soft rubber tip and that is what
    it took to clear out the pilot jet- the real tough one. Rebuilt it
    without a carb kit and it runs great now.

    That reminds me... what's usually in a carb rebuild kit? Just new
    gaskets/o-rings? Worth getting?

    Here's what I got in my CB360 Keyster carb repair kit, claimed by Sirius
    Consolidated, Inc. to be suitable for CJ360T.

    jet needle (probably wrong size)
    main jet (wrong size)
    idle-mixture screw with O-ring and spring
    float valve needle
    float valve seat with 0-ring
    bowl-to-body O-ring
    idle jet
    plastic washer

    why not just poke a wire thru it as frequently recommended by that hack Hoyt
    I am just joking!

  8. Have I ever told you that gargling with Berryman's B-12 will prevent
    the common cold, diabetes, heart disease, myopia and sexually
    transmitted diseases? Just kidding. Don't try that at home, kiddies...

    B-12 is to CV carbs as oat meal is to arteriosclerosis, except you can
    feel the results immediately.

    I am NOT an owner or shareholder in Berryman's, but that product is
    handy because it comes in the liquid form as well as in aerosol cans
    and you can get it anywhere in the USA. You don't have to run around
    looking for xylene and acetone in hardware stores, the stuff is right
    on the shelf at Wal-Mart and most auto parts stores. Berryman's has
    been around for at least 60 or 70 years, it's an old stand-by product

    Yes, I could barely see light through both old idle jets, but not the
    same amount through each, and not nearly as much as I could see through
    new jets. That was true both before and after my cleaning attempts. I
    didn't mention it above, but I was able to stick a long plastic bristle
    from a brush through the jet. That didn't seem to do any good---I did
    it without first soaking in carb cleaner, but I wouldn't think that it
    did any harm either. Maybe the deposits have to be softened up before
    the bristling would do any good.

    I gave up and called a local shop to order new jets. The guy seemed
    averse to selling new ones and brushed off that idea and told me to
    bring mine in and he would clean them in five minutes. He stuck a steel
    wire through the dry jets. That didn't seem to do any good, so then he
    soaked them in carb cleaner and again stuck the wire through. Now I can
    see about as much light as I could see through the new ones, but still
    not the same amount through each. Should I assume they are ruined?

    I see Mikuni "BS30/96 Series" Pilot Jets in the Dennis Kirk catalog:


    There is a photo of three jets, and mine look a lot like the one on the
    left. The verbal description in the catalog is the same for all the
    thirteen sizes of the jets---supposedly they all have six holes and are
    all 14mm long and all look like the one in the middle. I tend to assume
    that those descriptions are wrong, consistent with the general chaos and
    derangement of the Dennis Kirk catalog.

    Would these BS30/96 Series jets seem to be the right jets for my Honda?
