Personally here is what I do.
Change the oil and spray a little engine oil fogger in it while cranking it with the spark cut off. Then I siphon the gas out and use it in my wheelers.
That it, I don't subscribe to the "gas is only good for 30 days" crap, Even E10. We have had E10 for 15+ years in Minnesota and I've never had it "go bad" in under a year. I use the same method for all my other 2 stroke and 4 stroke toys and haven't ever had an issue though I HAVE upgraded the fuel lines and gaskets to Ethanol friendly stuff on older equipment.
Also sometime during the summer I like to pull the skid out of the sled and go through it and lube it to make sure everything is ready for another season.
