Seem it starts and runs fine for about 5 mins or less then starves for fuel. Carb makes a sucking sound when throttle up from idle and dies if throttle not feathered back. Seems after it sits for a while it will crank up and run fine. My guess is water in fuel, or air lock? What are your expert opinions. Currently won't start. Will wait a few and try again shortly. On trailer so no emergency. |

Fuel pumps working fine. But my gas smells more like alcohol. I think I have water in my tank. Will flush it out well and try again later. Removed air filter and there was small pool of water in intak openimg. |

Definitely water in fuel. I drained fule line with electric fuel pump. Fuelnin line was murky looking. Should I run good fuel through engine quickly to avoid internal corrosion? Or wait till tomorrow when I have the time? |

For future reference you can shine a flashlight in your tank at night and if you see what looks like diamonds in the bottom that would be water. Sounds like another ethanol casualty! |

I would take the bowl cap off bottom of carb & pump new, clean fuel into carb & let some wash right on thru. Put the cap back on & run for a few minutes. Good luck. This gas these days sucks ass. |

I keep marine grade Stabil in my tank and it's the real deal. Try it Mr. Guidry. |

What Owen said plus add a water/fuel separator. Not expensive and easy to install. Had to do it on both the boats I have with merc outboards. Saves a lot of headaches. |

Cleaned out gas tank. Washed out with gas treatment. Let dry overnight. Filled with new fuel. Changed in line filter. Yesterday, I had drained all the gas lines. Started first crank today and running very nicely. The gas I drained from the tank was very opaque/murky looking...dirty as hell. The gas and water had separated in the tank with the bad stuff at the bottom. Lesson learned. I'm in the market for fuel/water separator/filter. Now, what to do with 5 gallons of bad gas? |

Over here the parish dump will accept hazardous waste from residents (tires, batteries, oil, gas, etc) but only in small quantites. |

Give it to a GD owner since they were invented before the fuel filter

get one of those fancy funnels with the water screen in it and put it in your car or something. If my boat gas sits too long I just pour it into my gas guzzler 4.7L V8 jeep and its gone in no time (unfortunately). |
