hey guys new to this site. looking for direction on a carb problem. my 13 year old son just picked up his firs quad a 03 blaster. didnt run good so i took it in and had the carb cleaned and checked out (135$). he has rode it for about a week but it still doesnt idle good,takes a long time to rev down, and seem to have no power band -sometimes kinda a dog - the tors wires i removed from the carb and the throttle. any other ideas.
