Holley 94 ECG, rebuld but problem

[Bruce Lancaster]

Yes, a second complete venturi at the point of lowest pressure in the big venturi.
On these carbs, it is built into the removable nozzle bar, replacing the slanted type used about 1952--early Y blocks.
So far I haven't gathered much info on the later Ford E carbs...there are a lot of variants!

That's called an "annular discharge booster venturi", it was one of the big improvements compared to a 94.

Yes, it's the same as a booster. A smaller venturi in the middle of the main venturi.

Ok,

Unofrtunately I do not have 57 jets but 55, I have tried, and big improvement!
