Hey all gotta a question for ya. I have an 02 40hp merc. Just the last few trips I have had trouble getting the engine warmed up. Starts fine but then as I give it some throttle it dies. So I have to let it basically idle real rough for a min or two and then it will smooth out. Once I get it going it has been fine the rest of the day. Do you think I just need the carbs cleaned, new primer bulb? Any ideas? Thanks
