vacuum secondary prob.
I am running a dual holley setup on my z and prob. is the vacuum secondaries dont operate together(not even). I have found secondary covers with hose nipples on them.Was told to put these on and connect together with a piece of hose and it will equalize them. Do these work? or a waste of $

Connecting the vacuum secondary pots will balance the vacuum signal to both pots but will not solve a problem with one of the secondary diaphram's seal or the seal between the diaphram pot assembly and the carb body (small round cork gasket).
Check the secondary throttles for free movement also.
A over-thick carb base gasket can cause the throttle base plate to warp and bind the throttle shafts. So can corrosion.
