hi guys. i have a 1988 force 125. it has 2 carbs. i notice that the bottom carb. drips gas i don`t think it happens all the time,or just when it`s running. i also notice that it will drip for a short while after i`ve trailered the boat and have the motor tilted up. does any one know what would cause this? it`s been going on i think for a few yrs! THANKS>
