So this is my first year owning a Z and I am about to winterize it in the next couple of days. I have 200 hours on it so it is still pretty new. I am going to put stabil in the gas tank and fog the engine but to my main question, is there anything I need to do to the hydro's for winter? Anything else I'm missing besides the stabil, fogging, cleaning and greasing for winter for the Z? Also, I have a sthil FS110 4-Mix and I have used it for one season (approx. 25-50 hours). I was wondering if I need to get the valves adjusted or anything special for winterizing (lost the manual) besides fogging and stabil in the tank?
