Most likely when the machine ran out of fuel it sucked a piece of trash up into the carburetor Jets and now the carburetor will need to be removed and cleaned.

Remove the carburetor Bowl and clean the bowl nut with carburetor cleaner and a small wire and see if this will help before removing the entire carburetor
