Have you checked the pump shot? It`s supposed to give it a shot the very instant you move the throttle. Sometimes they can have a dead spot and a bog is the result. You may also want to check the pump cam is in the correct position. In the past when I had a bad pump shot it worked if you very slowly moved the throttle, but if you did so quickly it bogged. I checked the pump there after and found it had a hole in it.
