Edelbrock 1406 secondary venturi cluster

"It has more vacuum on that circuit due to the air flow actuated top set of butterflies. (that upper set opens by airflow overpowering the weights that hold them closed) (They are not mechanical)
Because of this, that opening is capable of a much higher flow than we would think by just looking at it.

If you were to open that tube up your 095 jet could very well act like a 120 due to less resistance.

If you really think there is a fuel supply issue there and you are determined to re design their carb for them, pull out those counterweighted butterflies and rejet bigger for the missing vacuum. (Then you may need to open those tube inlets up)
This way you will have more flow of fuel and air both through the secondaries.

You started this thread by saying you were trying to eliminate a bog situation, and then changed to say you were not concerned about the bog but were curious about the openings.

Seems both questions have been answered multiple times.


Ok, redo, mulligan or whatever you want to call it.
After reading your other posts on the two carbs 1405 and 6, it is now clear that you know more about it than your initial post got across.
I was under the impression that you were fairly new at this stuff from the question asked about the venturi tubes being different.
My oppologies, as this is clearly not the case.

Nice work.

Carry on. :D
