i have a 35 merc i just bought at the beginning of the season.. i was just wondering if anyone have ever heard of mercs not running too nice at trolling speed or if there is something wrong.. it seems like i have to crack the throttle to get gas to it every so often so it wont stall.. could it be a sticky carb or maybe new plugs would be the answer.. any help would be awsome.. i really need this trolling speed.
