I can’t tell if your kidding, if you are ignore what I’m saying lol. Your top fitting on the slave carb is fuel going out to the receiver carb plate. On the receiver carb opposite nipple is the return for both carbs back to the fuel tank. Back to the slave carb, the bottom fitting with the arrow facing the carb, is your fuel in, wether it be direct from the tank or a fuel selector switch. Just remember the arrows always point which way the fuel needs to flow. It should run how I explained it, if it doesn’t you have other problems. As far as the popoff being high, my opinion is that it needs high popoff to be able to provide sufficient fuel flow to the receiver carb after it has gone throughout the slave circuitry. I have personally setup a set of these carbs recently reverse jetted with a traditional lower popoff and it rips.

Am I miss reading the arrows then? Your pic shows the same way I run mine, with the fuel going into the 'OUT' arrow.
For instance on a single 38 you have the carb hooked up via the arrows. But on the dual carbs you have them opposite or it will not run.
I took her out yesterday and ran her with the pop off set the correct way and going to try it again with the pop off set testing from the out arrow.
Should probably just toss them and pony up for some new 46's..
