I have a 2002 2 cycle 50 hp Mercury which runs rough at idle, both cold, and once it warms up. It runs normally at higher rpm's and does not seem to miss out. However, once you drop back below 1200 rpm's or so it starts missing out. Any suggestions? Thanks.

It sounds like the idle mixture is rich on the carbs have they been adjusted lately
