No offense, but that video was freakin horrible, pretty much useless. By the time the injectors start spraying the camera jumps and moves away in an instant. Could you get us a longer video, or at least one where the camera doesn't move away as soon as the important stuff starts happening? Also it looks like they were pulsing. With no sound I can't tell if that was three quick stabs of the throttle or if it just randomly sprayed three times under steady throttle.
A proper spray will be a nice even cone of mist, there should be no "blobs" or "drips" or a stream or anything of the sort. These injectors do go bad somewhat commonly now in their old age, and it will run like a pig. What other symptoms do you have besides what is not clearly visible in this video? What makes you think it's flooding or running rich, what led you to suspect the injectors to begin with?
