Good morning all.<br />I need advice on this minor concern of mine. <br />As most of us do for the winter, I added sta-bil to each tank of gas. I asked marina guys to winterize both engines for me. While winterizing engines they too added a different brand of gas stabilized to each tank. I still have not used all of that gas, 1/2 tank left. <br />After adjusting each carb, marina mechanic suggested to add carb cleaner to fuel tank as it is running a bit lean. I am a little worried that it will be too much of additives. Will help or will harm? <br /><br />Enjoy boating/fishing weekend
