about 3 weeks ago i blew one of my reeds on my blaster stock reed cage. today i was riding trying to get the carb adjusted and it would bog hard at idle over half a turn of the air screw. a few minutes later it bogged down really hard and died. i drained the gas into a plastic tub and go figure it was bad and completely seperated. i put in fresh gas and nothing happened. pulled out the reed cage and one of my almost new reeds was busted. am i doing somethign wrong here? why did this happen again?
