I think the kit you are talking about has both pilot and main jets. Pulling the baffle will help it breath a touch better. If the carb you put on has an air/fuel mixture screw you might try adjusting that more on the richer side (counter clockwise). See where you're at first by turning it all the way in and count how many turns you have. If its close to 3 turns out already then you will want to try a larger pilot jet.
