Water is heavier than gasoline, so unless you are certain you are drawing from the very lowest place in the tank, you can't be sure you're not just getting the fuel off the top. I don't know how your tank fill is oriented with respect to rainwater runoff, but you might have gotten very little or you might have gotten a lot of water in the tank. One thing is for sure - if there's water in the tank, it will find its way to the carb at the least convenient moment.

Water will separate very clearly from the fuel. It will look like little clear blobs in the bottom of a glass jar. Were this my situation (as it has been in the past), I'd get the fuel from the lowest point in the tank I could reach, pump a pint or so in a glass jar and let it settle. If there's water mixed with fuel, you'll see it.
