I've got a 89 60 horse mercury. Yesterday wouldn't run worth a crap under 4800 RPM's cleaned the carbs last night and put new plugs in . now she won't even get up past 2200 at any range. did find something interesting in the carb though, the splash guard to the atmospheric jet has been broken off(2nd owner of boat) Any help would be greatly appreciated.<br /><br />------------------
