I just put a new piston in my boat and new gaskets but there is gas leaking somwhere and I can't find it any help would be nice the motor is a 120 force made by mercury it is a oe02 ss number with 2 carbs. I think I need a rebuild the lower carb. plus while braking the motor in I would idle at low diff. speeds but when I had over the hour and half the boat want up on plan ok but seems like that it had a little miss I think this might have to do with that fuel leak thanks chuck
