Yes, that could very well be your problem. Over time auto fuel tanks can accumulate a lot of water. This water settles to the bottom of the tank (which is usually a few inches above the fuel pickup). Hence, siphoning gas from your auto can result in water fouled fuel.
Anyway, drain your tank, fuel line, and carb and try starting over with fresh gas from a gas station. This may not fix it, but it sure can't hurt...
