If it were mine I would top it off with fuel and run it. I have tractors that sit for years with same fuel they start and run instantly. Our Cobra sits a lot we never drain fuel because I know it will burn. In all these years have never had an issue with bad fuel other than the ethanol being hard on soft parts especially in very small engines.
I do use the Fitch fuel catalysts in all our vehicles including tractors
