It sounds like your motor is starving for fuel. At an idle, you have adequate flow to keep the engine running. When you call for more fuel...you sputter and quit. Could be a clogged filter or trash in the line or in a jet. Yes you will have some air in the bulb, but not a great deal. You could be sucking air at a hose connection (loosing some prime)...try this, start the engine and slowly accererate, have someone pump the bulb as you accelerate, see if the engine works properly while doing this test.
