massive reconfiguration time again.

I wasn’t going to make any comments about tuning or adding holes to the air door, since I have zero experience with those particular carbs.
I can tell from some responses from others, that their experience with carbs that utilize spring loaded secondary air doors(avs, TQ, Q jet) is the same as mine.
In that...... when it bogs, the door is opening too fast.

It does seem odd to me, based on previous experiences with spring loaded air door carbs, that the proposed solution is to make the door open sooner.

I’m not saying it’s not the correct solution...... I’m simply saying, if that is the solution, it’s contradictory to what I(and apparently others as well) have found to normally be how you go about eliminating the bog on that “style” of carb.

Be interesting to see how it all shakes out.

I think this problem might be unique to a dual quad application. I think the same thing is everybody else, the problem is the doors are not opening or barely opening. My thought is that the vacuum signal just getting taken up by not only two primary but having to split what's left between two secondaries??..
I have some options as in just disconnecting the rear secondary function. Also I could spring load those door so they won't open under any circumstance.. if you read that article though they have a 409 and I have a 410 and they're using it in a dual quad application. Like you like dyno's and everything..
I just got my confirmation that my four air doors will be here on Thursday next week so it won't hurt to give it a shot I have plenty to spare..??
