It acts like a carb issue, and I believe it IS somehow a fuel/air/carb issue. If I crack the throttle open and hold it, it will kill the engine if I don't let off. The part that puzzles me is that it acts the same with either of the two carbs that I just tore down, soaked in cleaner, cleaned meticulously, reasembed properly and adjusted perfectly. One is the Rochester B I've run for the past six years. I'd bet money it's air/fuel related, but the fact that it acts THE SAME with BOTH CARBS makes me think it's pre or post carb. At this point I'm lost.
