[QUOTE="ossagp, post: 209914, member: 1650"] bad reeds can let the fuel air mix get pushed back into the intake and pick up fuel going both ways. The dry tip that is trying to turn gray is cleaning it up on top it looks like, but the blackened body and porcelain say it is sloppy. a weak spring on the needle or bad needle and seat can do that too. both tend to make the bike worse at low rpms than higher ones.
