Gentlemen, I'm looking for some advice on a problem I'm having with one of my twin 150s that began a couple weeks ago. It idles rough and stalls....always cranks back up but idles low and stalls often. Also I can smell/see fuel and oil in the water while flushing the engine. I have changed spark plugs, fuel/water seperaters. Any advise on where to look would be appreciated, Thanks- Josh
