I have a mid-70's 85 HP merc outboard. It runs great at WOT but really stumbles and runs rough at part-throttle. It feels like one of the carbs is kicking in intermittently and the other carb is working OK. When I open er up everthing runs smooth.<br /><br />I'm thinking a carb R&R. Anyone else have any ideas?<br /><br />Thanks!
