Eddy 1406 Questions

Trying to remove the lean bog from my car I wanted to look at how the butterflies looked and were the T-slot was set. So I pulled the carb and noticed that I have an exceptional amount of T-slot showing. So I readjusted and put the carb back on. I started the car and it barely idled now and was around 400rpm.

So my question is.. Do Eddy carbs have to have the T-port sync like Holley carbs? Is there another adjustment on the secondaries to help compensate for the idle? Or is that only a Holley thing?
