Quote: The 750 Edelbrock I speak of was a vacuum secondary carb.
Actually, it's not. It's airflow sensing thru the secondary and uses a counterweight or spring to counteract the air door's tendency to flop open. Holleys use a pressure drop off the primary bores to open the secondaries, hence the name vacuum secondary.
72, do try not to sound so ignorant and insecure about things...lol
wha? I never said a eddy 750 is vacuum...I know how it works,.
That was directed at me. I realize that it's not a "vacuum" secondary carb, just a reference that most everyone uses. I was just pointing out and clarifying what carb I was speaking of that I worked with, that it wasn't a double pump.
The "72" part was directed at you.
