i have a 97 sportster w/ 720 eng. w/ 2 carbs after idling 10 min. carbs start to drip out the venturi on top of throttle plates. I have cleaned carbs new gskts. and seals,fuel needles w/ no luck, seadoo dealer said "you probably wont get rid of that fuel drip" thanx, I called a nother dealer and they said thats strange, Ive never seen that before" . both carbs drip together and stop dripping momentarily if revved up and return to idle then start dripping again. Anybody heard of this? thanx.
