Re: Quadrajet percolation.
The next time you try to start it when it's hot, push the pedal to the floor and hold it there. Then try to start it. If it's percolation, you should be able to get her to fire without having to let her sit by HOLDING the pedal to the floor. Whatever you do, DO NOT pump the pedal!!! The earlier Q-Jets had a valve in the rear of the carb that aided it in starting for just this purpose. Why they did away with it, I'll never know.
