But I never did much tinkering on it, because it would start right off and run fine. Go to the mountains to snowmobile the next weekend and it wouldn't run! Finally I caught on what was happening when I noticed the clear plastic fuel line had ice crystals in it. I started adding a little Heet to the gasoline and never had another problem. That's precisely what was happening to my plane that cold Christmas Eve morning. I'd used Heet in my cars 50 years ago but got out of the habit. I'd never seen ice in the fuel of my planes either, in 30+ years of cold weather flying... except that once.
Agree with you. If you have a boat in Alaska, you better inspect the fuel for traces of water before you get it in the water. During the winter any water in the fuel or fuel lines will freeze, so most people pour a can of Heet in the tank every now and then (the red color can seems to work better in extreme cold weather). SeaFoam does about the same and more, since it does not contain alcohol. It has gotten quite popular around Fairbanks in recent years.

It won't light no matter what you do because the vapor is what burns. Drop the match in the fuel and it puts it out, just like water. Heat the fuel a few degrees and it will burn.
You are correct. But since the fuel injectors atomize the gasoline, which is then vaporized under pressure by the time the spark reaches it, it burns just fine in that state.

Best to keep eye wash bottles around if one works around batteries and/or fuel. Stuff happens. Enough water applied fast enough and no long term damage will be incurred. Painful though.
