SOURCE: 9.8 hp mercury outboard shutting off in low idle speed.

My problem ended up being the spring on the reed valve being weak.But at the same time and while I had already had my carb broke down I took a can of carb cleaner to it and cleaned it. In order to replace the spring on reed valve you will have to buy a new one, but don't worry I only payed about $6.00 for mine. You may also look into replacing your primer bulb if you haven't already because may allowing air to build up in your gas line while you are basically idiling.Once you get the carb straightened out you may have to reajust it again. If I might be able to help you again you may contact me at [email protected].
