Is this snow blower ruined?

I have reason to believe that this snow blower Troybuilt Storm 2410 never had end of season maintenance performed on it, and was likely stored with gas and oil left in the unit for 2 seasons now. I am worried about contaminated gas or oil in the engine and am scared to start it... is there anything I can do? I am not an engine person at all, so I am trying to find out what my options are. Does this need to go to a small engine repair shop, or am I over-reacting?



Thanks
