The one person that said he takes his carburator apart is probably trying to protect the diaphram and passages. Like I said in the last message......I might try that next winter. I know when gas used to have lead and some other additives the carbs would get gummed up when not in use. I had seen it many times because I worked in a lawnmower shop many years ago. It was not uncomman to see several carburators gummed up in the beginning of the year. I have not had a problem with gas now in several years. My lawn mower and snow blower and tiller and weed wacker and chain saw all get the same treatment which is none and they are stored in the out building with no heat or a/c. My generator is in the garage but has had no special treatment and still runs great. In the days of leaded fuel I tried gasoline stabilizer and it seamed to make matters worse. Of course, maybe I'm just lucky not doing anything special. I do make sure the gas used for my planes is reasonably fresh. If someone has something to add or take away from what I just said I will listen. I don't claim to be a know-it-all and am always open to more thoughts and ideas. Bill
