I'm parttime and have about 7 accounts I do. I got a Quick 36 Samurai last November and was only able to put 3 hours on it before storing it for winter. I cleaned the deck, filled the tank and put in a fuel stabilizer. The manual said I needed to dissconect the spark plug wire. I never did this. Does it matter? Do I need to change the oil before I start in april with only 3 hours of use on it? Anything I need to do before I start it up in the spring with the hours I have on it. My first commercial mower and want to take care of it. Thanks.
