    1 is as per this throat and air jets 17C2ACDF-590C-42DC-8580-23901FED6FFF.jpeg
    3 are like this,.
    I have 4 -94’s, 3 are identical in the throat, 1 is different, see pics.
    Anyone know if this is OK, or should I change the one

    The top one is a good candidate for a secondary carb in a multi carb system because the idle circuits tend to be a little on the lean side.
     
  3. what are the markings on the sides and ends?

    2 have no markings, been polished off! 1 has a Ford in an oval, (that’s the top one) and one has a Ford in a large square.i think they all have 94 on them

    The front LH carb is the different one
    These are going on a Man-A-Fre manifold, they are all primary carbs.

    Here's a little education. None of them are Strombergs. They are either Chandler Groves, Holley, or Ford.

    Def not an expert, but recently adopted my fathers Model T which have 4 Holley 94/2100s so have been doing a ton of research as they needed a rebuild. The attached may help in identification. I understand from my reading that even withing the Holley 94 models there were a few variations.

    Interesting little screws coming out of the access plugs for the jets. I'd take the top of one carb and look-see what they do. The nozzles in the top pic are later design. Can't remember the reason for the change.

    They were for a leaner idle. Look at the 3 air bleed holes whereas the other picture shows only one bleed.

    Those look like adjustable main jets to me.

    That is what I thought, seems like they might be needles to adjust main jet flow.

    Yes, they have adjustable mains. Can the odd carb be retrofitted with the same nozzles as the other 3?
