That is a very good possibility. You might take the top off and check to make certain your float isn't falling too far down. Gas evaporates in there (especially in a hot/dry spell) and the float can fall far enough down so the needle becomes sort of "cocked" in the seat piece. When that happens the float can't shut off the fuel flow as it has been designed to do. Raise the float "down" adjustment about a sixteenth of an inch and see if that helps.
edit: when you tap the float bowl with a screwdriver, it will usually be enough to free the needle up and let it work okay again. It will run really rich and badly until it normalizes.
