White smoke in cars is usually water, the same would apply here.
Probably why it idles fine is that the gas will float on top of the water, but when you run at higher rpms, the gas and water in the float bowl of the carb will start to mix, and water will also get into the engine.

White smoke in cars means water from the cooling system. Water in fuel will not run. It can, if it mixes enough to run, cause a backfire, but otherwise it would just not run. Remember, gas floats on water, and the carb pulls from the bottom of the bowl. If the bowl has water in it, it WILL NOT run at all. White smoke on this engine does not mean water in the fuel. Same does not apply at all, the engine is air cooled. White smoke is likely not really white in this case, unless the fuel is just junk, or has some kind of additive in it. It is likely oil that has crept into the engine from non use, and the fact that the rings will likely have to reseat. New fuel and some run time and most likely it will go away.
Drain and clean your fuel system. Come on, if you see water in it, that's a given. Follow Yosemite Sam's advice and you'll be fine.
