I have 6 champion generators I maintain for myself and neighbors. I use Lucas oil treatment for the cylinder. Position piston to bottom and tilt generator so that cylinder is vertical as possible. Warm up oil treatment to make is more fluid. Just under tbs in cylinder, allow to spread few min. Slowly pull cord few times and install plug. Ethanol free gas is preferred for small engines to reduce corrosion. If not available I make my own using high octane gas with ethanol and separate the gas and ethanol with water and a mister funnel
