[QUOTE="Gotem, post: 307574, member: 9901"] The most important thing is to not run old gas. The gas today is crap. The ethanol is suppose to make up 10% of it, but there are stories where its actually been significantly higher. The shelf life on today's gas sucks and it is worse with 2-strokes like yours. Some believe the ethanol reacts with the oil mixed in with the gas and makes it drier in the sense it does not do its job of lubricating as good. Go to a few marine repair shops and ask them if they have encountered many issues with today's gas and 2-stroke outboards. They will all probably tell you horror stories. You have the whole phase separation where the ethanol separates from the gas and then bonds with water. The alcohol being an excellent solvent can loosen vanish from the carb and then plug it up. I personally unplug the hose from my 1970's Johnson and let the gas run out. I also am always filling up my 6 gallon fuel tank within two weeks after using up all the gas. If it was going to take a month to use up a 6 gallon tank, I would switch to two 3 gallon tanks. [/QUOTE]
