Just fired it up and noticed rough idle. Pulled plugs and found that last cylinder was full of water.
What keeps water from filling the cylinders when exhaust valves are open and engine is not running?

Also, is it bad to have hose running while engine is not? Please tell me I don't have big troubles %(
