I would like to add to the av-gas comments. I would really avoid using so-called 100 LL. We have forgotten the problems created by lead in the fuel and our little engines are not designed for it. Granted most of us don't burn enough to matter, but lead deposits can gum the rings in all and foul the oil in your 4-stroke in a hurry. To say nothing of the plug. Try and stay with 87 octane "auto-gas". If I was looking to buy fuel at an airport I would start at Airnav. A little weird to find your way around at first. Find an airport, then scroll down to see what fuel is available. Should also give hours attended and other info to save you a wasted trip. The pertinent links: http://pure-gasoline.com/ http://airnav.com/ Just remember.....buy your gas and leave. If you start hanging around at the picnic table watching planes you could end up with a whole new addiction. Mike (recovering)
