I got lazy last winter and didnt stabilize my 3/4 tank of fuel before layup. Dropped the boat in today for a shake down cruise. Boat was hard to start and ran rough. I feel pretty sure that it must be bad gas. There's probably 10-12 gallons left in the tank. What do u do with bad gas?

Do not burn it! My job is for Midwest Can which is a major supplier of fuel/gas containers. You would not believe the number of law suits we get from incidents involving using gas on or starting fires.
I will typically pour old gas into a oil drain pan and let it evaporate. |

i go thru this every yr. stabil or not. keep the boat still for a day. i drain my fuel out or siphon. try and get it all out, the water is on the bottom. i dry it as best i can i then blow out the fuel line and clean the carb(thats where the jelly is ) clear all jets , and anything that you can for passageways I add dry gas and a bit of fresh fuel . to be honest i let the old gas seperate for a day or so in 5 gal buckets and then either return to the boat . mower. or truck and burn it up i have appr 15 gas powered things and it works every yr although its usually only one or two carbs that seem to suffer from a winter.

The fuel grades must be completely different elsewhere. I know Tim always has issues with stabil or not. I have never once used the stuff in a sled, boat, or car. Every year they fire right up and run perfectly on whatever was left in the tank when I parked them. My sled sat for 3 years almost and the fuel I pulled out of it smelled exactly like the new stuff I mixed and filled with for good measure.
If I have any old gas I do what Peter does. Put it in the nearest lawnmower I can find ha. The old Farmall runs great on nasty fuel. My stuff has been stored in heated and cold storage and nothing seems to make a bit of difference. |

I cant get gas to last more than a few months in anything, stabilizer or not. The boats will sometimes run on the gas, but they wont start. A fresh shot down the carb does the trick. I try to drain and run dry prior to lay up when possible. Other times, I drain after storage and put it in the truck or lawnmower.
I tinkered with a friends '87SN last year... it hadnt been in the water in several years. It started right up on the old gas- I couldnt believe it. That tells me that fuel is getting worse, at least around here! After a few months of sitting, its a safe bet that it will smell like paint thinner. |

Also try and store with minimal fuel which get's treated at the end of the season, when I am ready to run again I add fresh gas 5 gallons at a time.
Unless it looks and smells completely bad, may be worth a shot to add some fresh fuel and fuel treatment and see how it runs. |

After the first spring fire, I always go fill it completely up before I head to the water.

I think you are on to something, of all the gas powered stuff I have, cars,chain saws,mowers,snowblowers,tractors,boats etc the only thing I have had trouble with is my Stihl weed whip . Those old Internationals and Fords I think would run on paint thinner! |

Haha exactly Gary, The old tractor don't care ha. The 67 gets a little pissy on storage fuel if you try to romp on it. If you run it up to the big rpm numbers it will break up slightly in the cooler spring weather until you give it some fresh pump premium.
Who knows what the big oil guys do to fuel in different regions. |

around here we get this weird jelly (sometimes clear sometimes pink)in the carbs and bowls and main jets here. i see small engines run up and down on the governors sometimes a carb /main jet cleaning sometimes i add 20% sea foam and watch it slowly improve before my eyes.

Peter, I agree with Seafoam. When I rebuild small engine carbs that have sat for a long time they grow this white fuzzy stuff on the inside. You can use carb cleaner (dip or aerosol) and scrape it but traces of it are still there. Run fuel through it and it still looks the same. Run fuel through with Seafoam and it cleans it like the day it was new. I will run a half a can through the boat and the truck once a year for good measure.
