I got a 1985 Force 15 outboard as part of a boat deal. The motor runs fine once given a bit of gas but at the idle speed, out of gear or in gear the motor coughs about every 5-10 seconds and will die if more gas is not applied. I have trhe manual for it but am not sure where to start the diagnosis. Is this a carb related problem or an ignition issue at low idle? Any help in diagnosing is much appreciated.<br /><br />Thanks,<br />Kevin
