72 Duster Resurrection

I put all my bad gas in my lawnmower. The gas of today is worse! I have to clean the carb almost every time I mow (weekly out here with no rain) because of the ethanol jello that it leaves behind. I have a beater Mazda pick up that I have not put gas in in 2 years. I start it up every 2 months for about 15 minutes to scare the cats out and burn off the spiderwebs. No problems but it smells funny. If you can extend the fuel line below the tank, it will siphon most out once you get it flowing. Do what you feel is necessary but I dont know what your going to do with 5 gallons of bad gas. Bonfire?
