Save your money, fogging sprays are expensive, and get a bottle of Marvin Mystery Oil. When you look at the ingredients, it's all hydrocarbons. Instead of spraying inside the carb, just pour this stuff in directly. I've done this for years, as well as 1000's of other boaters, and have all great results. This stuff is a lot thicker than the fogging spray and, IMO, coats better and will adhere longer.
