The vent hole is in the top of the carb in between the jets.
Why would one need a jig?
I don't see how even enlarging the vent hole would reduce pressure. It raises the risk of getting debris in the bowl. There is just a screen for protection.
I really think that the perculation is just from the heat of the engine rising from the engine, not from pressure build up.
The manifold gets really hot and the carbs become heat risers.
Heat isolator gaskets are mandatory and all that are really needed.
The Gene Berg valves are just added insurance.
