Quote: Also, I think that the bleed port for the vacuum secondaries is above the throttle plates near the venturis, so its unafected by idle vacuum or pulsating vacuum like on race cammed engines......they only work when the vacuum singal is strong when throttles are open and engibe is revving.....
So the balls are there just to restrict excessive singal to the diaphragm to prevent a BOG due to the secondaries opening too fast (on a mild engine), and to open up the bleed passage to aid in faster closing of the secondaries when singal at the venturi drops to atmospheric.....
I guess Im cool leaving those out as long as my HEMI doesnt bog when those things open fast!
I think you just answered all your own questions.You even figured out the linkage bar.It can be adjusted to even help facitilate opening the secondarys.
