i've got a 20hp merc year2000, i installed a 25 carbon this motor wich worked fine with a little air flow adjustment. last week i installed boyesen reeds, now the motor is flooding, my buddy has the same motor and also installed boyesen reeds and they worked fine. there is gas running out of the carb and when it does run it smokes like hell, i tried adjusting the air screw this doesn't seem to help. i'm stumped.
