I would start by turning it 1/4 of a turn in and testing , and then keep turning until the bog goes away. If you end up with the screw all the way in with no improvement, you either need a larger pilot jet or need to clean the pilot jet and passages... If you go out 1/4 of a turn and it's more than 3 turns out, you could try a smaller pilot jet. Usually, low end bog is because of a lean condition, and turning it in a bit solves it pretty quickly...
