I've been looking at carb tuning and came across this following couple of videos that I thought might be of interest to others too.

They show a 4-barrel carb on a dyno and it would appear at full throttle, the acceleration pump circuits are continually feeding fuel. I've also been pointed to the following description of the phenomenon.

Although this seems to indicate its a problem mainly occuring in 4-pots?
(article shows a 2-barrel unit)
Someone suggested to me that it was quite normal and safe as it made the motor rich, but I can't help but think you're gonna be up against it trying to evaluate main jet sizes IF there is a steady stream (or not) from the acceleration circuits.
So has anyone experienced this issue?
