You may have solved my mystery. My wife has a little PT Cruiser she bought at an auction for far less than it's worth. Uses it to run to town. We had a long cold winter and it refused to start no matter what I tried. She drove other vehicles. This spring it hit high 50s one day and she jumped it again and cranked and it fired. She said she her liquid running for a few seconds after it started. Maybe a fuel line was iced up tight all winter. She burns the 10% ethanol. I'll have her switch to real gas, she only burns a tank every few months anyway.
I rebuilt a 1980 golf cart for use around the place. It was great for years then one day someone dumped in ethanol gas and the carb parts dissolved and it hasn't moved since. Sigh.
Sadly, the way to scavenge the moisture out of the fuel system is to add even more ethanol. Wait until the tank is down and add a bottle of Heet (NOT ISO-Heet), it comes in a yellow bottle. That will absorb water in the system and you can 'burn' it with the ethanol. Then, fill it with the no ethanol gas. If there is an in-line fuel filter, I'd replace that also, because water tends to settle in such, only to expand and cause problems when it freezes.
You should be able to either get a rebuild kit for the carb or another carb, and get the golf cart back up and running again, provided it doesn't have other troubles.
One other thing, it pays to keep fuel tanks full, because there is less room for contracting fuel and vapor to pull in moisture through the vent in the fuel cap. An empty tank will have more head space, which means the internal pressure of one just left to sit will cycle with temperature during the course of a day, and over time that can put moisture in your fuel system, too. If it's going to be sitting over 6 months, use a fuel stabilizer like Stabil to keep the gas fresh.
