1988 Yamaha 130, Boat sat for 12 months, would start but would not idle. I rebuilt the carbs and put on a new fuel pump. It now starts easy and will idle but idles very rough. I noticed that fuel was dumping out of the top left carbs main nozzle and then out of the front of the carb, I have attached a picture below pointing to the carb and nozzle. The nozzle almost reminds me of a water fountain spitting up water. I dont see any of the other three nozzles pouring out fuel like this. Any ideas why this is happening? Thanks!
