On some Q-jet carbs if not most if you lightly floor it the rears will not open up at times. Generally you'll have to punch it to get them to open. This can be due to the rear linkage has a leg - or foot if you call it on the out side of the linkage, this keeps the back barrels from just opening up every time you go past 1/2 throttle not punching the gas pedal like your going to pass someone. It can be removed, but for the performance aspect you will suffer more in the fuel economy.

On a properly adjusted quadrajet that lock would be released after warm up. That lock should on keep the back barrels closed until the choke has released if the pull off is correct. The throttle plate will open when you push down on the pedal BUT, the top butter flys may not. Depends on the setting, they can be adjusted to open as early as you want. To early and you will get a big bog. The rear butter flys on a holley carb has a diaphragm and spring that can be tuned, the quad just has a spring that can be adjusted as necessary. most box store rebuilts have too much spring pressure, keeping the rear butter flys closed too long. Last thing you want is the BOG on a heavy vehicle like a MH.
