I've got a flat spot. Cruising down the road at part throttle, if I quickly open the plates a little, or even if I'm just gradually opening the throttle, I get instant response (pull), dead spot, then pull again (all in a split second). I think it's running out of pump shot as I can feel that get used, then nothing, and then it pulls again. Does this sound like the case?
Or, might this be a power valve issue? It has about 5-6" vacuum at idle and I'm running a 3.5PV.
I'm not a carb guy so if you need more info, let me know.
