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,.
