Gasoline additive for carb messed up from sitting?

Yes, non ethanol is definitely what I like to use. We have two stations here that sell it. And I always use the additive in the tank prior to storing.

But I didnt do it last time, so now I have the problem. I don't think Stabil will "fix" anything, maybe nothing will, but if there isn't an additive for this type of thing, there should be!

Im looking for a fix, not how to prevent this from happening. It already has!
