[QUOTE="DaveKamp, post: 205189, member: 5122"] Sweating on the outside of the carbeurator, is usually the result of gasoline leaking THROUGH the aluminum. it's a die cast part. Castings are naturally porous, and exposure to non-gasoline will frequently 'etch' a pathway into some porous spot, which allows the thinner compounds of a fuel blend to find an easy path through. Why would it happen? In the die casting process, metal is melted, and then injected under hydraulic pressure into a mold. If there's some sort of contamination in the process (typically, it's in powdered form, and frequently, carbon soot from oil vapors), it'll get impregnated into the casting. It'll be fine for a long time, but eventually, exposure to a variety of things will cause the contaminant to disperse. Ethanol is great at facilitating things like this, but ANYTHING will do it eventually... And you have a 'sweaty bowl'... The first thing I'd do, is look for a replacement bowl and put that on... with a new gasket. [/QUOTE]
