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.
Carburetor Squirting - Tech Articles - Stock Car Racing Magazine
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?
