My 305 TPI is starting hard at times, but the biggest problem is that when I crack the throttle open the engine kind of "stalls" and then goes through a series of hesitation like symptoms where it is acting like it wants to rev up but can't. The problem seems to be better or at least less apparent after I have let the engine warm up real good. I have corrected a couple of vacuum leaks including the EGR and my Cold Start Injector, but no joy. I have ohmed out the plug wires and they are good. Engine vacuum is 21 in -Hg and steady and fuel pressure reads around 30-32 psi. I do have a video file I could provide that may help with showing what is going on.
