Gee, could it be bad gas?

So, I bought this old boat from a guy who had it sittin' with a full tank of gas for... I dunno.... 2 years maybe? The engine just won't run smooth for some reason. Keeps backfiring. Won't idle. Won't accelerate. For the life of me, I just can't imagine why. :lol:

I wonder how well that would actually work? ;)

As it is, I don't really have any way to dispose of all this bad gas. I'm guessing on order of 30 gallons or so. I am siphoning it into 5 gallon buckets and just leaving it outside to evaporate. Maybe I could keep a bucket full as a general parts cleaner/solvent. The stuff is so bad, it barely fires the engine.

Oh, and I primed the fuel separator with fresh gas and ran it for a few more minutes, and it suddenly started running better, even though it was still mixed with some of the old stuff. Then after that, back to backfiring, and stalling.

I think it could be bad gas at two years old, especially if it has ethanol in it.

Looks bad to me!! For disposing of the old gas, call your local waste disposal site. Our local "dump" has a recycling station for hazmat like oil, fuel, paint,etc., and they take it for free.

Listen very closely, that faint squealing is the carb crying for a rebuild...that stuff does bad things inside a carb. Regarding "primed the fuel separator with fresh gas", always put on a fresh filter/separator, there is no reliable way to drain or clear them. Kind of like putting on 2 day old underwear after a fresh shower.

I had some 5 year old gas recently (actually about 6 months ago) and it looked just like what you have........ I just filtered it carefully and put it in my car (about 2 gallons of "bad" to 10 gallons of "good" or so) and burned it. Couldn't tell any difference.

At $4/gallon, I wouldn't just throw it away.....

It's sitting in dirty 5 gallon buckets outside. I wouldn't put this garbage in an old rusty lawnmower.
