The dome springs need attention.

 

Open up the domes and check the spring rate. The one in the front looks like it has a spring that is worn. The best way to check is to open up both (make sure you keep each dome with its respective carb) and check the heights against each other. It is possible to stretch the spring slightly to make them match, but don't stretch it too much, they are delicate. I went with stiffer springs and (fingers crossed) it should give better mid-range. Let us know.

Port Matching is usually done on the cylinder head side, not the carb side. You would match the carb side for 44mm Z carbs, but IMHO, that is too much carb for a 4 cylinder L series motor. If the carbs and maniflod need matched, do a progressive taper from the 44mm outside edge to the 38mm of the manifold. Venturi effect will cause the velocity of the air/fuel mixture to move faster at the end of the taper, and "force" the air/fuel mixture into the combustion chamber.

thats the good ontake with the adjustable balance tube nice finde

 

Not quite a balance tube, like a Z car. Its an air adjust for smog purposes. If the old adjuster screw gets corroded, too much air gets in, and the carbs are near impossible to adjust. Nissan offers the screw as part of the linkage rebuild kit (99996-D1110), but I happen to have it as part of the "parts not needed" pile in my stash of stuff. PM me and I would be happy to trade for some small trinket of equal or lesser value. NIB part with spring.

 

BTW: Plug the hole above the PCV, not needed for your carbs, unless you have the original air cleaner. Use the PCV, if you get the chance. You will have to fab a hose to work, but it does help reduce the smell in the underhood compartment.
