The bog on the AVS II should be able to be tuned out with a twist of a screw driver. Tightening the air door to the point where it won’t open to allow a bog.
The AFB has a the counterweighted air door that needs to have more weight out on it and since no one is willing to try more weight, and where do you start?????
The bog remains.
Perhaps, just perhaps, if you didn’t slam the throttle down so hard but just gave it a medium rapid depressing, it won’t act like chit. This allows the secondary air door to open slowly without bogging. Slamming the go pedal rips the secondary door open and the pump **** can not cover it. The pump **** has only so much fuel delivered so fast for so long.
What to do with the AFB & AVS II?
Sell the carbs you have, roll the money over into a new Holley and stand up in front of your friends and say,
“I need a Holley because I can’t tune the Edelbrock and I hate the short comings of it.”
And be done with it and move on.
