I am dealing with a 1987 Sea Ray Seville powered by a 3.0 L Mercruiser, my problem is not the initial start-up.....this is fine. The problem is with the re-start after shutting it down for a while. It runs fine for a few minutes then starts to miss badly....Once I was able to work through it by playing with the throttle.....usually it stalls and there is a strong fuel smell....I can only start it by holding the throttle wide open as you would if you flooded the engine.... I do know that it is not due to the choke not opening.....any ideas? Thanks
