Re: mercury carbs
jimzx9r <br />Your Motor is a 1971 model. More than likely, your middle carb float is sticking or out of adjustment and allowing fuel to flow when it's not supposed to. Best thing to do is get a hold of a Carb. kit and clean and rebuild the carbs. This should take care of your problem. Also pick up a Manual, if you don't have one, which will guide you through the process. Best to do all the carbs while your at it, as the others probably need some attention also.
