The fact it was under a carport def helps. Always a possibility engine could be seized but being a 2 stroke I doubt it is. Your biggest issue is what’s in the carbs. Prob some nasty gum and varnish to deal with.

How I’d go about it, and take this with a grain of salt because I’m absolute lunatic with maintenance and upkeep...🤣

Pull all the plugs and shoot some oil in the cyls. Turn over engine by hand to be sure it’s moving. Drain the carbs float bowls if you can. Pull off fuel lines from carbs to filters and blow them out with air. Change filter and water separator. Disconnect fuel line from tank and put in a portable tank with fresh clean gas. Don’t forget to pre mix your oil if it’s not oil injected. Pump primer ball till it’s hard (insert joke here) and crank her over.

At this point you’ll see where your at running wise. Lots more to take care of but that’s a starting point. Hope that helps. I wouldn’t worry about discarding that bad gas or cleaning the tank just yet until you know where your at.
