As an ex small engine mechanic, I'd advise against using a 2 stroke for something like that. A 4 stroke would be a better bet. Better yet would be a natural gas/propane 4 stroke, since gasoline goes stale and plugs carburetors.
Small diesels could be an option but they're harder to pull start for a given size.
