have been trying to track down way this '86 120HP<br />Johnson runs rich at idle for a while now. Over the weekend I noticed when I took of the air box that it was very wet on the inside. When i started it with the air box off i noticed it was spitting gas - one spit about every 3-4 seconds from each of the 4 carbs' idle air bleed jets. <br />what mibht cause this???
