vacuum gauge to solve idle issue

Thanks again, I didnt get a chance to pull the carb, but I had 2 Eddys, so I looked at them to make adjustments to T-ports. I played with fast idle screw and Idle screw to get the T-ports basically "square". I dont see an "air bypass valve" on either of the Eddys, or the Carter, that you mentioned in your T-port synchro how to?
Back to work this weekend, so not sure when I can get to checking/setting the valves. Hopefully by the end of the weekend. I will also pull Carter off engine and take a look at the T-ports.
Am I correct in that the only way to adjust T-ports is to adjust idle screw and fast idle screw? I will post pics shortly, on the one Eddy, the T-ports look like they are different sizes?
Thanks again!

As always, I start with the T-port sync. It pretty much sets the idle-timing for me. But with a solid-lifter cam, I start with checking the lash.
