Smaller rods will richen mix. Larger jets will richen mix. Stronger springs will richen mix. Easiest is the rods that pop out the top with that small torx or screw flanking the air cleaner stud. The higher hole in the acc pump lever is the larger shot (or the one closer to the fulcrum). They make em rich so they dont run lean and hurt customers motors or run bad out of the box. I bet its rich. I think if you put something over the air horn while idling and your lean, the idle will go up slightly, not so for rich.
