Where do my secondary jets go?

    Obviously I didn't take enough photos during disassembly.

    I know there are secondary jets for this carburetor, as they are sitting on my bench. I looked at the manual and some online pictures but they all show the secondary jets at the back of the fuel cell.

    But my carburetor has no such spot.

    The only place I can see that they might go is way down this slot, where there is a threaded hole to receive them.

    Any thoughts?

    I can see where the threaded hole is supposed to be, but it isn't there.

    and whats the part number of carb ? front passenger side lower . might look like #9305S or #8715S etc . 4 digit and letter perhaps .
    there has to be route for the gas to travel up from fuel bowl to the secondary nozzle assembly . follow the passage ways . or you can shoot some wd40 or whatever slowly into the upper feed hole and can see where it comes out in fuel bowl ( hopefully ) . i'll try and post a couple passageway pics .
    what are the jet sizes ? normally the fronts are larger due to the rods , rears smaller . you didn't have extra jets laying around that may have gotten mixed in with your parts ?
    edit ; some pics . pic #1 - typical edelbrock/carter rear nozzle assy and where it goes , #2 - add wd40 etc here and watch for lower fuel bowl evidence , #3-#7 primary and secondary passageway pics to give ya an idea of the fuel path to follow . #6 and #7 show the primary path , notice how the rod goes right under jet to pick up fuel and then travels up to primary nozzle . drills don't bend , they'll be straight and intersect each other .

    They are in the rear where those slotted holes are. Most ALL original AFB's had them there. Don't make the mistake, like many do, of putting the larger ones in the rear, they go in the FRONT. When Edelbrock repro'ed the carbs. they moved the secondary jets to the outside for easier access.

    so it must pick up fuel from the casting "tube" gap in the rear just behind the baffle ? looks like the well plug is maybe just to the outside of that and it looks like a straight shot in to jet port .
