    Ok I took the top off, double checked float level and float drop. I made some minor adjustments for both. Put it back together and it's still leaking. I don't know if I said this - but it doesn't happen at idle - only while I've driven. That's why I'm sure the fuel is rising up and sloshing into that channel.
    I think I found what might be the issue. The kit came with three different needles. I used the short one from what I read on the manufactures website. However I may have just misread something (as I do). I just read a thread on the exact same issue I have - the problem was resolved by using the needle with the little spring button on it. (see photo)
    I'll take it apart again and try the springy one, and report back.

    Simple Omissions; Great Frustrations

    Of such simple mistakes or misunderstandings are great frustrations built.

    There was this missing head bolt ...

    I had one of those missing head bolts. It seems that I forget about it oh every 30 years or so!

    It will almost run (for a little while) without it.

    Luckily mine was "found again" while trying to take the head off a few months back when I did the valve job. I wasn't prying too hard when suddenly I remembered that damn hidden bolt!

    Ok I finally got to this... sorry life gets in the way of my jeep sometimes, dammit.
    Replacing the needle and seat with the "springy" one seems to have solved the issue.
    This seems quite trivial but the fuel sloshing seems to have stopped. Still I'd think this was a combination of float level/drop and the needle/seat but I really didn't adjust the float all that much. Well anyway... so far all is good.

    For such a simple machine, they sure can be fickle now and again. You are correct that it was a combination of the two, but you should be good to go now. Life has a funny way of dragging down project progress.

    You are doing okay. My CJ3A hasn’t progressed much since I pulled the transmission and transfer case in March 2018. Earlier this year I managed to finish disassembling the transfer case.
