I pray someone can help me. I have a 1999 mercury 90hp ELPTO 2 stroke (3 carburetors). It was having a real problem running. It would stall, then quit after a few minutes of running and couldn't be re-started. Thank goodness for Seatow. I replaced the fuel lines, cleaned the carbs, cleaned the fuel tank, new spark plugs, and had the fuel pump rebuilt. Same problem. I then had 3 separate mechanics tell me that it sounds like the stador had gone bad. I replaced that with a used one that was in good working order. I have a solid spark on all 3 plugs. It still will not start unless you spray starter fluid in the carb. It will then start and run. Could someone give me any idea why this is what it is and how to fix it? I want to go fishing/duck hunting and time is the only thing running over here.
