Cats all have their own personalties and idiosyncrasies, sometimes Billie was such an affectionate cat, she'd just jump on a chair and want big lovvin' but the rest of the time you could feck right off.
Floods! You sure? I know a lot of these tiny Walbro etc. carbs have some sort of control valve in the bottom, I'd imagine if this is stuck or broken then it could flood it.

Modern fuel is crap, too much ethanol etc. If left it'll just sit in the fuel system eating all the seals and turning into incombustible gloop. If it's not going to be used for a month or more we're advised (by Walbro) to drain the tank and run 'em dry. Seems a bit excessive to me so mine only get run dry at the end of the year.
