Listen to the hippie! Don't try to start it without doing something first. You'll pump crappy jello gas into your carb/fuel injectors and all lines. Go to the auto parts store and buy yourself two cans of Sea Foam. They cost about nine bucks a piece. Stuff works miracles. It will clean out the tank dump a can in the tank. Then add some gas and let it sit. Once you start it, burn out all that gas and fill up the tank and dump the other can in. You can also put it in the crank case with oil.
