What do you guys do for end of season service. So far i've heard everything from "just drain gas" to "it's too complicated and you should take it in for someone else to service it"

ahh 'putting the snowblower away' that's music to my ears.
If it's running fine, Drain the fuel is all you should have to do, (this year I have to oil the track chains on mine). Next year, add fresh fuel, start her up till warm, change oil, if it's hard to start I'll change the spark plug.
