Getting ready to put the equipment away for the season, and am wondering what you guys do to winterize all your equipment??? I put some gas stabilizer in the tanks, take the spark plug off, put a couple of squirts of oil, and then give it a couple of pulls. I read in an earlier thread that you should change the oil. I usually wait till the spring and change it before first usage??? Should i be changing it before i put it away for the winter???
