Re: gas removal from carbs and lines
In general, each carburater has a bolt on the bottom which holds the float bowl in place. Removing the bolt (center botom of the float bowl) will allow you to remove the float bowl and toss out the gas. Don't tear the gaskets. If indeed you have water in gas, you should be able to see it as clear bubbles if you pour the gas into a bell jar or other clear container. Alcohol in the fuel can absorb the water and make this reading a little fuzzy.<br /><br />Use a non-electric pump (a hand pump or a siphon) to remove the fuel from the fuel tank. Remove as much fuel/water as possible as the water will be down at the bottom of the tank. You should be able to see the extent of the fuel in the water, and run it in small amounts by adding it to another vehicle, farm tractor, lawn mower, whatever. If your state has oxgenated fuel (alcohol added) you can probably even safely add a bit at a time to a fuel injected car. I hope we are only talking a few gallons here.<br /><br />Finally, with new fuel in the tank, pump the hand bulb with the check valve open at the end of the hose which attaches to the engine until you get gasoline only coming out that end.<br /><br />You may have a little water in the engine but that should steam off as you burn your new mix.
