If it's a mechanical fuel pump, you can pinch off the supply hose to the pump and run it. If the results are favorable, then OJH is probably correct.
As an aside, after running the engine out of fuel, the float will be settled to the bottom of the bowl and the needle valve will be at it's most open. When you restore the fuel flow you may have the potential of flushing clear any debris. I have had limited success doing this. Of course the piece of debris if it does move off is now in the bottom of the bowl but it may never cause you any issue...
